Description

带透射光栅和反射光栅的波导及其生产方法
技术领域
本公开涉及波导器件，具体涉及全息波导显示器。
背景技术
波导是一种能够约束和导引波(即限制波的传播空间)的结构。光波导属于其中的一个子类，其具有能够导引电磁波(通常为可见波谱中的电磁波)的结构。波导结构利用多个不同的机制控制波的传播路径。例如，平面波导可利用衍射光栅衍射入射光并将其耦合到波导结构中，使耦合光能够通过全内反射(TIR)在平面结构内继续传播。
采用可在波导内记录全息光学元件的材料体系制作波导。其中一类材料包括聚合物分散液晶(PDLC)混合物，所述混合物含有光可聚合单体和液晶，其另一个子类包括全息聚合物分散液晶(HPDLC)混合物。用两束有相干性的激光束照射材料来将体相位光栅等全息光学元件记录在这类液体混合物中。在记录过程中，单体发生聚合，混合物进行光聚合诱导相分离，产生液晶微液滴分布密集的区域，中间散布着透明聚合物区域。富液晶区和贫液晶区交替出现，形成了光栅条纹面。通常将由此得到的光栅称为可切换布拉格光栅(SBG)，其所有特性通常与体光栅或布拉格光栅相关，但结合其在衍射效率(衍射到预定方向的入射光所占比例)连续范围内的光栅电调谐能力来看，其所具有的折射率调制范围要高得多。后者可从非衍射(清除)扩展到衍射，效率接近100％。
适合在一系列显示器和传感器中使用上述波导光学器件。在很多应用中，利用各种波导结构和材料体系来生产带一种或多种光栅层(编码多项光学功能)的波导，可在道路运输、航空和军事用途的增强现实(AR)和虚拟现实(VR)近眼显示器、紧凑型平视显示器(HUD)和头盔式显示器或头戴式显示器(HMD)以及生物统计和激光雷达(LIDAR)的传感器领域中使用所述波导来实现新的创新。

具体实施方式
在对实施例进行说明时，为了不使本发明的基本原理变得复杂难懂，我们省略或简化了光学设计和视觉显示器领域技术人员所知晓的一些众所周知的光学技术特点。除非另有说明，否则相对于光线或束方向的“轴上”术语是指本发明中涉及的与光学元件表面垂直轴线相平行的传播。在以下描述中，可将光、光线、束和方向互换使用并相互关联，以指示电磁辐射沿直线轨迹传播的方向。术语“光”和“照明”涉及电磁波谱的可见光波段和红外波段。将在以下各部分内容中采用光学设计领域技术人员通常使用的术语进行说明。在一些实施例中，本发明中使用的术语“光栅”可包括成组的光栅。应当理解的是，为了方便说明，除非另有说明，并非按比例绘制附图。
波导技术能够实现适合不同用途的低成本、高效率、多功能的衍射光学解决方案。在某些实施例中，实现了一种包括至少一个透射光栅和至少一个反射光栅的波导显示器。可在不同的光栅层之间或在单个光栅层内实现透射光栅和反射光栅。在一些实施例中，透射光栅和反射光栅采用复用型光栅。复用透射光栅和反射光栅可用于以多种角度支撑透射光栅的特定用途，这在典型布拉格光栅中则无法实现支撑。在几个实施例中，可利用这类结构制作用于波导的高效率反射输入光栅。
在某些实施例中，复用反射和透射光栅能够提高激光均匀性，即减少波导中出现的带斑及其他照明伪影。其原理为：作为波导内的束传播过程，波导反射面与反射全息图之间发生多重反射，从而促进了照明平均化。在一些实施例中，为了减少激光照明的波导中的带斑，可设置一个与复用光栅重叠的分束器层。分束器可由一个或多个介电层提供。在几个实施例中，分束器可对一种偏振敏感。在另一个实施例中，分束器可对S偏振敏感。在某些实施例中，分束器可以是一层抗反射覆盖层，经过法线入射优化，当浸入玻璃或塑料中时，所述抗反射覆盖层具有高全内反射(TIR)角反射能力。
在制作包含透射光栅和反射光栅的波导时，可采用各种系统和方法。在某些实施例中，制作这类光栅所需的系统可包括至少一个光源、一个提供光源零级束和至少一个衍射级束的母光栅、一个支撑与母光栅重叠的一层全息记录材料(例如但不限于HPDLC材料)的基板以及一个与全息记录材料层重叠的至少部分反射面。在记录操作期间，可由至少部分反射面反射衍射束。结合零级束、衍射束和反射束产生的干涉，可以同时记录透射光栅和反射光栅。在某些实施例中，透射光栅和反射光栅采用复用型光栅。在某些实施例中，系统包括一种HPDLC混合物，混合物包含弱介电材料，能够在不产生多余反射(因此称为伪光栅)的情况下，实现反射和透射光栅的高效率复用。在几个实施例中，配向层重叠可用于对HPDLC复用反射和透射光栅形成进行微调。例如，在某些实施例中，可利用HPDLC光栅的选择性配向，平衡复用透射光栅和反射光栅的折射率调制和/或偏振响应。在某些实施例中，配向层可用于提升反射光栅中的S偏振灵敏度。在典型的波导实施方式中，富LC条纹(在典型HPDLC光栅中与布拉格条纹平面正交)的平均专用轴垂直于波导反射面。当光以典型波导全内反射角经折叠光栅传播时，这种取向有助于产生较强的相互作用力。
实现透射光栅和反射光栅的波导实施例适用于各种应用场合。例如，某些应用场合宜采用小尺寸、大视场、大Eyebox的全色彩波导。在以往的彩色成像解决方案中，堆叠两个或多个单色波导，其中波导各自支撑一个光栅层，光栅采用单色。在很多情况下，可将每个波导进一步用于输入图像调制光，在二维中扩展光的范围以及从波导中朝向Eyebox的方向提取光。然而，在波导堆栈中进行重叠光栅的配向时，这类多波导堆叠方案要求的公差非常严格，从而导致生产良率较低。尝试采用一层传播红光、第二层传播绿蓝相间光的双层方案，但是在生产过程中，这种解决方案仍然存在配向问题。因此，本发明的很多实施例都以用于实现大视场、单光栅层彩色波导显示器的方法和架构为主。波导和光栅架构、全息记录材料以及包含透射光栅和反射光栅的波导实施例将在以下部分进行更加详细地讨论。
光学波导和光栅结构
波导中记录的光学结构可包括很多不同类型的光学元件，例如但不限于衍射光栅。光栅可实现各种光学功能，包括但不限于耦合光、导光和防止光透射。在某些实施例中，光栅是指位于波导外表面上的表面浮雕光栅。其他实施例中实现的光栅是指布拉格光栅(也称为体光栅)，即能够进行周期性折射率调制的结构。可采用多种不同的方法制作布拉格光栅。其中一种工艺包括全息光聚合物材料的干涉曝光，从而形成周期性调制的结构。布拉格光栅能够在有较少光被衍射成较高级光的情况下实现高效率。通过控制光栅的折射率调制(一种可用于制作在大瞳孔上提取光的损耗式波导光栅的特性)来改变衍射和零级束中的相对光量。光栅可用光栅矢量进行表征，光栅矢量将光栅条纹的取向界定在波导平面内。光栅也可以用三维空间中的K矢量进行表征，如果是布拉格光栅，则K矢量是指垂直于布拉格条纹的矢量。K矢量可确定给定输入角和衍射角范围内的光学效率。
一种用于全息波导器件的布拉格光栅为可切换布拉格光栅(SBG)。SBG的制作方法是，首先将光可聚合单体和液晶材料的混合物薄膜置于两个基板之间。基板可由玻璃和塑料等各种材料制成。在很多情况下，基板采用并行配置。在其他实施例中，基板呈楔形。一个或两个基板均可支撑电极(通常为透明氧化锡膜)，可用于在膜上施加电场。SBG中的光栅结构可利用干涉曝光配合空间周期性强度调制，可采用光聚合诱导相分离法将其记录在液体材料(通常称为浆液)中。产生的光栅形态和性能是由辐照强度控制、混合物中材料的组分体积分数和曝光温度等因素(但不限于此)决定的。需要理解的是，可根据给定应用场合的具体要求，使用多种材料和混合物。在某些实施例中，采用了HPDLC材料。在记录过程中，单体发生聚合，混合物发生相分离。通过聚集液晶分子来形成离散或聚结液滴，所述液滴按光波波长周期性地分布在聚合物网络中。富液晶区和贫液晶区交替出现，形成光栅条纹面，由于液滴中液晶分子的取向呈有序化，产生具有强光偏振的布拉格衍射。
由此产生的体相位光栅可表现出很高的衍射效率，衍射效率可以通过施加在膜上的电场大小进行控制。通过透明电极在光栅上施加电场时，液晶液滴的自然取向会发生变化，导致条纹的折射率调制降低，同时全息衍射效率下降到很低的水平。电极的配置通常可使外加电场垂直于基板。在某些实施例中，电极由氧化铟锡(ITO)制成。在无外加电场的关闭状态下，液晶的专用轴一般以与条纹垂直的方式进行配向。因此，光栅对P偏振光表现出高折射率调制和高衍射效率。在向HPDLC施加电场时，光栅切换到开启状态，其中，液晶分子的专用轴以平行于外加电场的方式进行配向，因此垂直于基板。在开启状态下，光栅表现出对S偏振光和P偏振光的较低折射率调制和较低衍射效率。因此，光栅区不再进行光的衍射。根据HPDLC器件的功能，每个光栅区可划分为多个光栅元件，例如像素矩阵。通常，一个基板表面上的电极呈均匀和连续状态，而相对基板表面上的电极图案按照所述多个可选择性切换的光栅元件进行构造。
SBG元件通常在30μs内切换清除，开启切换的驰豫时间更长。可在连续范围内通过外加电压调节此器件的衍射效率。在很多情况下，在不施加电压的情况下所述器件表现出接近100％的效率，而在施加足够高电压的情况下，其效率基本为零。在某些类型的HPDLC器件中，可利用磁场控制液晶取向。在一些HPDLC应用场合中，液晶材料与聚合物的相分离可以达到不产生明显液滴结构的程度。SBG还可用作无源光栅。在这种模式下，其主要益处是独特的高折射率调制。SBG可用于提供自由空间应用所需的透射或反射光栅。SBG可以作为波导器件，其中，HPDLC在波导附近形成了波导芯或渐耦合层。用于构成HPDLC单元的基板提供了一种全内反射(TIR)导光结构。当可切换光栅以超出TIR条件的角度进行光衍射时，可以将光耦合出SBG。
在某些实施例中，从SBG中提取或抽空液晶来获得抽空布拉格光栅(EBG)。EBG可以表征为表面浮雕光栅(SRG)，由于SRG结构的深度(远大于通过表面蚀刻等常规工艺(常用于制作SRG)实际可实现的深度)，SRG的特性与布拉格光栅十分相似。有很多种液晶的提取方法，包括但不限于异丙醇和溶剂冲洗。在某些实施例中，需去除SBG的一个透明基板，并提取液晶。在另一个实施例中，需更换去除的基板。SRG可以至少部分地用折射率较高或较低的材料回填。这类光栅提供了适合各种波导应用的效率调整、角度/光谱响应、偏振和其他特性的范围。
根据本发明的各种实施例，所述波导可包括专为实现特定目的和功能而设计的各种光栅配置。在某些实施例中，所述波导的设计实现了光栅配置，能够通过有效扩展准直光学系统的出射瞳径来保持Eyebox尺寸，同时缩小透镜尺寸。出射瞳径指虚拟孔径，其中只有穿过该虚拟孔径的光线才能进入使用者的眼睛。在某些实施例中，所述波导包括一个光耦合到光源的输入光栅、一个提供第一方向扩束的折叠光栅和一个提供第二方向(通常与第一方向正交)扩束的输出光栅，以及朝向Eyebox的束提取。需要理解的是，已经实现光栅配置的波导架构可取决于给定应用的具体要求。在某些实施例中，任何实施例中使用的光栅可具有匹配的光栅矢量，以提供大小基本为零的合矢量。在一些实施例中，所述光栅配置包括多个折叠光栅。在几个实施例中，所述光栅配置包括用于同时进行扩束和束提取的输入光栅和第二光栅。第二光栅可包括具有不同规格的光栅，这些光栅用于传播不同的视场部分，并且设置在单独的重叠光栅层内，或在单个光栅层内复用。在某些实施例中，单个基板层的任一侧设有两个光栅层。此外，还可以使用各种类型的光栅和波导架构。
在几个实施例中，在设计中为各层光栅提供不同的光谱和/或角度响应。例如，在某些实施例中，重叠或复用不同光栅层上的不同光栅来增加光谱带宽。在某些实施例中，利用三个光栅层即可实现全彩波导，每个光栅层的设计可以确保其能够在不同的光谱带(红、绿和蓝)中运行。在其他实施例中，利用红绿光栅层和绿蓝光栅层两个光栅层来实现全彩波导。需要理解的是，这类技术同样可以增加波导的运行角带宽。除了在不同的光栅层上复用光栅外，还可以在单个光栅层内复用多个光栅，即可以在同一体积内叠加多个光栅。在几个实施例中，在波导中包括至少一个光栅层，在所述光栅层中采用在相同体积中复用的两个或多个光栅规格。在另一个实施例中，波导包括两个光栅层，在所述的每个光栅层中采用在相同体积中复用的两个光栅规格。利用各种制作技术来在同一体积内复用两个或多个光栅规格。在某些实施例中，将复用母光栅与曝光配置结合使用，形成复用光栅。在某些实施例中，通过对具有两种或两种以上曝光的光配置的光记录材料层进行顺序曝光来制作出复用光栅，其中，每种配置的设计可以形成一种光栅规格。在某些实施例中，通过使两个或多个曝光光配置交替出现，对光记录材料层进行曝光来制作复用光栅，其中，每种配置的设计可以形成一种光栅规格。需要理解的是，复用光栅可以采用包括本领域众所周知的技术在内的各种技术进行制作。
在某些实施例中，根据本发明的实施例，波导内传播的光会在至少一个光栅内部进行二元互动(即，光栅的设计使其在两个不同的入射角下具有高衍射效率或衍射效率峰值)。在某些实施例中，波导可包括以下至少一种光栅：角度复用光栅、彩色复用光栅、折叠光栅、二元互动光栅、滚动K矢量光栅、交叉折叠光栅、棋盘格光栅、啁啾光栅、具有空间变化折射率调制的光栅、具有空间变化光栅厚度的光栅、具有空间变化平均折射率的光栅、具有空间变化折射率调制张量的光栅、具有空间变化平均折射率张量的光栅以及具有空间变化双折射特性的光栅。在某些实施例中，波导可包含以下至少一种：半波片、四分之一波片、抗反射覆盖层、分束层、配向层、用于减少眩光的光致变色背层和用于减少眩光的叶窗膜。在几个实施例中，波导可以支撑为不同偏振提供单独光路的光栅。在各种实施例中，波导可以支撑为不同光谱和/或角带宽提供单独光路的光栅。在某些实施例中，可以采用HPDLC光栅、记录在HPDLC中的切换光栅(如可切换布拉格光栅)、记录在全息光聚合物中的布拉格光栅或表面浮雕光栅。在某些实施例中，波导在单色波段中运行。在某些实施例中，波导在绿色波段中运行。在几个实施例中，在不同光谱波段(如红绿蓝(RGB))中运行的波导层可以堆叠成三层波导结构。在另一个实施例中，各层堆叠时，波导层之间存在气隙。在各种实施例中，波导层在蓝绿色和绿红色等较宽的波段中运行，从而提供两种波导层解决方案。在其他实施例中，光栅经彩色复用后可以减少光栅层的数量。各种类型的光栅均可实现。在某些实施例中，每层中至少有一个光栅是可切换光栅。在某些实施例中，可采用弯曲波导。在几个实施例中，波导可包含梯度折射率(GRIN)结构。在某些实施例中，波导可以由塑料基板制成。
包含如上所述光学结构的波导可在多种不同的应用中实现，包括但不限于波导显示器。在各种实施例中，波导显示器采用大于10mm的Eyebox和大于25mm的出瞳距离。在某些实施例中，波导显示器包括厚度在2.0-5.0mm之间的波导。在某些实施例中，波导显示器可提供对角线角度至少为50°的图像视场。在另一个实施例中，波导显示器可提供对角线角度至少为70°的图像视场。波导显示器可采用很多不同类型的图像生成单元(PGU)。在几个实施例中，PGU可以是反射或透射空间光调制器，例如硅上液晶(LCoS)面板或微机电系统(MEMS)面板。在某些实施例中，PGU可以是发射器件，如有机发光二极管(OLED)面板。在某些实施例中，OLED显示器的亮度可大于4000尼特，分辨率为4kx4k像素。在几个实施例中，波导的光效率可大于10％，使用亮度为4000尼特的OLED显示器来提供大于400尼特的图像亮度。能够实现P衍射光栅的波导(即具有P偏振光高效率的光栅)通常具有5％–6.2％的波导效率。由于P衍射或S衍射光栅会浪费掉非偏振光源(如OLED面板)一半的光，因此很多实施例都以能够同时提供S衍射光栅和P衍射光栅的波导为主，使波导管的效率提高两倍。在某些实施例中，S衍射光栅和P衍射光栅在单独的重叠光栅层中实现。或者，在某些条件下，单个光栅可以为P偏振光和S偏振光提供高效率。在几个实施例中，波导包括通过从HPDLC光栅(如上文所述)提取液晶而产生的类布拉格光栅，从而在某些波长和角度范围内实现高S和P衍射效率，以获得适当选择的光栅厚度值(通常在2-5μm范围内)。

HPDLC混合物一般包括液晶、单体、光引发剂染料和共引发剂。此混合物(通常称为浆液)通常还包括表面活性剂。为了对本发明进行说明，将表面活性剂定义为降低总液体混合物表面张力的任何化学试剂。众所周知，可以在PDLC混合物中使用表面活性剂，其时间可以追溯到早期PDLC研究。例如，R.L Sutherland等人在国际光学工程学会(SPIE)第2689期，158-169页，1996中发表的一篇论文(其公开内容通过本发明的引用，成为本发明的一部分)介绍了PDLC混合物，包括单体、光引发剂、共引发剂、扩链剂和可以添加表面活性剂的液晶。Natarajan等人在《非线性光学物理与材料杂志(Journal of Nonlinear Optical Physicsand Materials)》第5卷第l期89-98，1996上发表的一篇论文中也提到了表面活性剂，其公开内容通过本发明的引用，成为本发明的一部分。此外，Sutherland等人发表的第7018563号美国专利讨论了用于形成聚合物分散液晶光学元件的聚合物分散液晶材料，该材料具有：至少一个丙烯酸单体；至少一种类型的液晶材料；光引发剂染料；共引发剂；和表面活性剂。所述第7018563号美国专利的公开内容通过本发明的整体引用，成为本发明的一部分。

丙烯酸酯具有在快速动力学上与其他材料混合良好以及与成膜工艺相容的优点。由于丙烯酸酯具有交联性，因此在机械上具有鲁棒性和灵活性。例如，已将官能团2(di)和3(tri)的聚氨酯丙烯酸酯广泛应用于HPDLC技术。同时还采用了更高官能团的材料，如五和六官能团。
包含反射和透射光栅的波导
参见附图，图中一般显示了与本发明各种实施例中在单个光栅层中实现全彩色的显示器或传感器相关的系统和方法。在某些实施例中，根据本发明原理所述的波导显示器包括至少一个波导基板、一个利用图像数据进行调制的光源、至少一个用于将光耦合到波导中TIR的输入耦合器、至少一个透射光栅和至少一个反射光栅，其中，反射光栅和透射光栅至少部分重叠。图1从概念上显示了本发明一个实施例中能够实现透射光栅和反射光栅的波导显示器。如图所示，显示器100包括一个波导101，其支撑一个输入光栅102(具有输入耦合器的功能)、一个透射光栅103和一个反射光栅104。在说明性实施例中，透射光栅103和反射光栅104至少部分重叠。在某些实施例中，可在单个光栅层中复用反射光栅和透射光栅。图2从概念上显示了这种波导。在图2中，所示显示器200包括一个波导201，其支撑输入光栅202、复用透射光栅203和反射光栅204。虽然在图1和2中给出了具体的波导结构，但仍可依据本发明的各种实施例实现各种配置和修改。例如，在几个实施例中，用棱镜代替光栅作为输入耦合器。如上所述，此类波导显示器可包括至少一个光源。在某些实施例中，光源能够提供图像调制光。在某些实施例中，根据数据进行调制的光源可包括至少一个以下项目：一个激光扫描投影仪、一个微显示面板和/或一个发射显示器。在几个实施例中，根据数据进行调制的光源可以提供至少两种不同波长的光。
图3从概念上显示了本发明一个实施例中的复用透射光栅和反射光栅。如图所示，复用光栅300包括一个具有条纹301的透射光栅，所述条纹由包含反射光栅的区域所分隔，其特征是低折射率302和高折射率条纹303。在某些实施例中，透射光栅条纹301的折射率可大于反射光栅的平均折射率。在其他实施例中，透射光栅条纹301的折射率可小于反射光栅的平均折射率。在某些实施例中，可选择折射率值，以便在透射光栅和反射光栅条纹之间产生各种折射率对比度。在图3所示的实施例中，反射和透射条纹与相互正交设置的透射光栅K矢量304(由符号KT标记)和反射光栅K矢量305(由符号KR标记)并非成倾斜角度设置。需要理解的是，其他实施例可包括一个或两个透射光栅和反射光栅，所述光栅具有倾斜条纹架构。
上述光栅和本公开所涉及的光栅可以具有各种结构，包括但不限于体光栅和表面浮雕光栅。在某些实施例中，每种材料记录了至少一个光栅，比如全息光聚合物、HPDLC材料或均匀调制全息液晶聚合物材料。记录的HPDLC材质反射光栅产生的布拉格条纹通常会很长，而且表面锚定性较差。在某些情况下，可能会使光栅结构分层。在使用HPDLC(如图4中的HPDLC)的实施例中，可提供允许具有由透射条纹支撑的液晶和聚合物锚定结构(306，307)的反射光栅。在某些实施例中，通过选择液晶和单体类型，将液晶和单体以促进液晶和聚合物之间牢固局部锚定的浓度进行混合来控制锚定强度。在某些实施例中，利用添加剂实现强锚定。使用术语“脚手架”描述利用一个格栅支撑另一个格栅的结构。关于促进高效锚定的化学和工艺相关数据和指导可参见HPDLC材料体系文献。
可采用多种不同的方式制作复用光栅(如图2所示的光栅)。需要理解的是，需要形成的特定类型的复用光栅可决定所使用的方法。图4从概念上显示了本发明一个实施例中用于记录复用透射-反射光栅的系统。如图所示，记录设备400包括：一个母光栅基板401、一个母光栅402、一个母盖玻片403、一个光栅底部基板404、一个全息记录材料的光栅层405、一个光栅顶部基板406、一个在基板408下表面上形成的部分反射层407以及一个滤光玻璃基板409。需要理解的是，可通过具有各种厚度的各种类型材料来实现各个层。例如，母光栅402可以是振幅光栅或体光栅。母盖玻片403可采用约1.1mm厚的光学玻璃。在其他实施例中，可使用不同的玻璃厚度和材料。光栅基板层404、406可采用Corning IrisTM玻璃，其厚度通常在约0.2mm至约1.8mm之间。在某些实施例中，光栅层405为微米量级，其厚度范围为约1μm至约5μm。然而，根据应用情况，可酌情确定其他光栅层厚度。在某些实施例中，光栅层405具有可实现特定光栅角带宽和效率的特定厚度。光栅层405的记录材料适用于记录任何类型的光栅，包括斜光栅和非斜光栅。此类光栅还可提供各种光学功能，包括但不限于将光耦合到波导中，提供扩束，并从波导中提取光。在某些实施例中，可采用抗反射覆盖层作为部分反射覆盖层407，当浸入玻璃时，抗反射覆盖层可提供高入射角的明显反射。在某些实施例中，可通过堆栈一个或多个介电层或包括介电/金属层来提供部分反射覆盖层407。部分反射覆盖层玻璃基板408可采用

Slim玻璃，滤光玻璃基板409可采用Schott R60阻挡玻璃。
在记录过程中，可照射母光栅402，形成零级光和衍射光。至少一部分零级光和至少一部分衍射光可在全息记录材料层405内共同形成干涉图案，从而形成透射光栅。可从部分反射覆盖层407反射至少一部分零级光，并与全息记录材料405内的至少一部分衍射光发生干涉，进而形成反射光栅。可在单个复用层中形成反射和透射光栅。需要理解的是，在某些实施例中，利用多个光栅层，可形成重叠的透射光栅和反射光栅
图5从概念上对本发明各个实施例中复用透射光栅和反射光栅的构成予以说明。记录系统500与图4的系统类似。与图4类似，记录系统500还可包括一个滤光玻璃基板。如图所示，由光线502-504表示的入射准直光照射母光栅501。母光栅501产生零级光线505-507和衍射光线508。零级光线505-507穿过光栅层509。从顶部基板511的上表面反射(510)一部分衍射光508，并与光栅层509重新相互作用。在说明性实施例中，系统500包括一个部分反射层512。在其他实施例中，可以不包括部分反射层。回到图5，部分反射层512的反射基本上要弱于顶部基板511上表面的反射。对于光栅的形成，照射和光路的这种配置和布置使零级光和衍射光发生干涉，形成透射光栅。例如，零级光线506可与衍射光线508发生干涉，从而在光栅层的一部分513中形成透射光栅。同时，反射衍射光线510可与零级光线507发生干涉，从而在光栅层的另一部分514中形成反射光栅。需要理解的是，图5所示的示意图并未示出系统中的每一条光线和干涉相互作用。根据图5所示的光路，应该清楚的是，可在光栅层上的每个点复用透射光栅和反射光栅。在某些实施例中，可(按顺序地或同时地)用多个入射准直束照射母光栅501，以便记录多组复用反射和透射光栅。在几个实施例中，可在母光栅上方在不同的点使用具有不同入射角的射束来照射母光栅501。在某些实施例中，可用扫描准直束照射母光栅501。在某些实施例中，可使用准直束照射母光栅501，准直束通过母光栅的光圈逐渐指向母光栅。
图6从概念上对本发明一个实施例中形成复用透射-反射光栅的另一种配置予以说明。此外，记录系统600类似于图4所示的系统。与图4类似，记录系统600还可包括一个滤光玻璃基板。与图5的实施例不同，在这种情况下，衍射光601在部分反射层602处发生反射，顶部基板603上表面处的反射要小得多。如图所示，由光线605-607表示的入射准直光照射母光栅604。母光栅604产生穿过光栅层611的零级光608-610和衍射光601。从部分反射层602反射612一部分衍射光601，并与光栅层611重新相互作用。零级光和衍射光可发生干涉，形成透射光栅和/或反射光栅。例如，零级光线609与衍射光线601发生干涉，从而在光栅层的一部分613形成透射光栅，而反射衍射光线612与零级光线610发生干涉，从而在光栅层611的另一部分614形成反射光栅。
虽然图5和图6显示了记录透射光栅和反射光栅的具体方法和配置，但是可根据给定应用的具体要求，相应地实现各种其他过程。在某些实施例中，使用多个光栅层，并且透射光栅和反射光栅不复用。多个光栅层可相邻。在某些实施例中，两个光栅层设置在单个基板层的任一侧。除了不同的记录和曝光设置外，还可以实现各种不同的过程。
图7显示了本发明一个实施例中透射光栅和反射光栅的制作方法。如图所示，方法700包括提供(701)至少一个光源、一个全息记录材料层和一个至少部分反射面。需要理解的是，可以适当地利用各种全息记录材料中的任何一种，包括但不限于HPDLC材料和各种光聚合物。在某些实施例中，反射面为全反射面。可以使用至少一个光源，形成(702)第一和第二记录束。在某些实施例中，利用单个光源形成第一和第二记录束。例如，将来自光源的单个射束指向衍射光栅来形成两个射束。在其他实施例中，利用两个光源分别形成第一和第二记录束。可将第一和第二记录束透射(703)到全息记录材料层中。可将一部分第一记录束通过全息记录材料层向至少部分反射面透射(704)。将第一记录束的透射部分从至少部分反射面反射(705)回全息记录材料层中。可利用第一和第二记录束在全息记录材料层中形成(706)透射光栅。利用反射的第一记录束和第二记录束在全息记录材料层中形成(707)反射光栅。在某些实施例中，可由所述至少部分反射面构成成品波导元件的一部分。在几个实施例中，仅在曝光时存在所述至少部分反射面(及其支撑基板)。
图8所示流程图从概念上显示了本发明一个实施例中透射光栅和反射光栅的第二种制作方法。如图所示，方法800包括提供(801)至少一个光源、一个包括单体和液晶的全息记录材料层以及一个至少部分反射面。利用所述至少一个光源来形成(802)第一和第二记录束。第一和第二记录束可以透射(803)到全息记录材料层中。一部分第一记录束可通过全息记录材料层向反射面透射(804)。第一记录束的透射部分可从反射面反射(805)回全息记录材料层中。利用第一和第二射束来在全息记录材料层中形成(806)透射光栅。可在透射光栅中形成液晶到聚合物锚定结构(807)来支撑反射光栅。利用反射的第一射束和第二射束在全息记录材料层(808)上形成反射光栅。
图9所示流程图从概念上显示了本发明一个实施例中透射光栅和反射光栅的第三种制作方法。如图所示，方法900包括提供(901)一个母光栅、一个支撑记录材料层的基板、一个光源以及一个相对于所述记录材料层与母光栅相对设置的至少部分反射面(即所述记录材料层位于至少部分反射面和母光栅之间)。可利用光源发出的光照射(902)母光栅。通过照射母光栅，可形成(903)衍射束和零级束。可从至少部分反射面反射(904)至少一部分衍射束。零级束和衍射束可发生干涉(905)，从而在记录材料层中形成透射光栅。零级束和反射束可以发生干涉(906)，从而在记录材料层中形成反射光栅。需要理解的是，实现图8和9中所述过程的系统和元件可采用类似于图7所述的方式实现。例如，在这些过程中，可采用类似的方式取代全息记录材料。
虽然图7-9说明了在波导显示器中形成光栅的具体方法，但是根据给定应用的具体要求，可实施很多不同的过程来形成此类光栅。此外，可对图7-9所示的方法做出各种修改。例如，可形成透射光栅和反射光栅作为复用光栅。在某些实施例中，通过对零级光和衍射光进行干涉，并用零级光干涉衍射光从部分反射面的反射光来形成复用透射光栅和反射光栅。在其他实施例中，零级光和衍射光的反射发生干涉，形成光栅。也可以在不同的光栅层之间形成透射光栅和反射光栅。
根据本发明的各种实施例，可通过各种光栅配置实现实现透射和反射光栅的波导。在某些实施例中，波导支撑至少一个输入透射光栅、至少一个折叠透射光栅和至少一个输出透射光栅。输入、折叠和输出透射光栅中的至少一个可与反射光栅复用。在其他实施例中，反射光栅与输入光栅和折叠光栅中的至少一个光栅相重叠。在某些实施例中，波导支撑第一和第二折叠透射光栅。第一和第二折叠透射光栅可彼此重叠，并与至少一个反射光栅重叠。在某些实施例中，第一和第二折叠透射光栅具有交叉K矢量。每个折叠透射光栅可沿第一方向对来自输入光栅的光进行扩束，并将其耦合到另一个折叠透射光栅，随后折叠透射光栅可在不同方向上对光进行扩束，并朝向观看者提取。
图10从概念上显示了本发明一个实施例中实现复用透射和反射折叠光栅的波导显示器架构。在说明性实施例中，波导显示器1000包括一个波导1001，使用所述波导支撑一个输入光栅1002、复用透射1003和反射1004光栅以及一个输出光栅1005。图中给出了输入光1006、波导光1007、第一方向扩束光1008和第二方向扩束输出光1009所使用的光路。在某些实施例中，可利用光栅结构在同一侧输入和输出光。需要理解的是，本发明的附加实施例可包括各种光栅配置。例如，图11从概念上显示了一种波导架构1100，其中输出光栅包括复用透射1101和反射光栅1102，而图12从概念上显示了一种波导架构1200，其中输入光栅包括复用透射光栅1201和反射光栅1202。图13从概念上显示了本发明一个实施例中的波导架构1300，其中提供了两个单独的输入光栅1301、1302。
可结合折叠和输出光栅的功能解决基于输入、折叠和输出光栅的常规波导架构中存在的一些关键问题。在某些实施例中，所述显示器包括一个波导，波导一个支撑输入光栅和两个进行扩束和提取双重功能的重叠光栅，每个重叠光栅根据通过波导传播的部分场进行垂直扩束或水平扩束。可以等边或对称配置布置输入光栅和重叠光栅的光栅矢量，从而提供基本为零的合矢量。图14从概念上显示了本发明一个实施例中的波导架构1400，其包括一个支撑输入光栅1402的波导1401和一个包括重叠复用透射光栅1403、1404和反射光栅1405、1406的光栅结构。在某些实施例中，在不同的光栅层中设置每组复用光栅。在某些实施例中，进一步相互复用所述两组光栅，形成四个复用光栅。在图14的实施例中，可将两个光栅配置为交叉折叠光栅(即在不同方向上具有K矢量的折叠光栅)，通过改变波导平面中引导射束的方向进行扩束。在更一般的意义上，可对交叉折叠光栅进行二维扩束并从波导中提取光。在某些实施例中，可将透射光栅配置为交叉折叠光栅。在某些实施例中，实现了两组交叉折叠光栅。透射光栅构成第一组，而反射光栅构成第二组。在另一实施例中，由每个透射光栅和反射光栅形成一组交叉折叠光栅。可将耦合到波导中的视场划分为第一部分和第二部分。在某些实施例中，第一视场部分和第二视场部分在垂直或水平方向分别与正角度和负角度相对应。在某些实施例中，可在角度空间中重叠第一部分和第二部分。在几个实施例中，视场的第一部分通过第一折叠光栅进行垂直扩束，在并行操作中，通过第二折叠光栅进行水平扩束和提取。
尽管图14显示了实现交叉折叠光栅的特定光栅配置，但是根据给定应用的要求，也可适当采用各种其他架构。例如，可采用各种不同的输入光栅配置。在某些实施例中，采用棱镜代替输入光栅。其他输入配置如图15和16所示。图15从概念上显示了本发明一个实施例中使用交叉折叠光栅的波导架构1500，其中，输入耦合器对透射1501和反射1502光栅进行复用。图16从概念上显示了本发明一个实施例中使用交叉折叠光栅的波导架构1600，其中提供了两个单独的输入耦合光栅1601、1602。需要理解的是，很明显，可在提供二维扩束的波导显示器中使用复用透射和反射光栅的很多其他组合。在某些实施例中，在交叉光栅结构中使用的复用光栅组中，可以省略其中一个反射光栅。
在某些实施例中，所述装置包括一个波导，其中，将输入光分成两个波长带，沿着分叉光路设置波长带，并且所述波长带各自具有专用的折叠光栅。可使用一对重叠的输出光栅来提取光，并为每个波长带分配一个光栅。输出光栅可具有相互成90度的光栅矢量。可采用表面浮雕或全息型光栅。在某些实施例中，所述装置包括一个支撑重叠衍射元件的波导，光栅矢量沿同一方向配向，以便进行水平扩束和提取。光栅可夹住电活性材料，实现清除和衍射状态切换。关于交叉光栅波导架构，本公开可包含第16/709,517号美国专利申请(“提供单光栅层彩色全息波导显示器的方法和装置”)和第14/620,969号美国专利申请(“波导光栅器件”)中公开的实施例和指导，所述第16/709,517号美国专利申请和第14/620,969号美国专利申请的公开内容通过本发明的整体引用，成为本发明的一部分。
可通过从Eyebox到图像源的反向光线跟踪确定规格和材料特性。可由透明基板支撑光栅层。基板可采用高折射率材料、光学玻璃或塑料。在某些实施例中，采用弯曲基板。可由第二基板覆盖光栅，第一和第二基板形成导光结构。光栅可分为单独的光栅元件，每个元件具有不同的材料和光栅特性。至少一部分光栅元件为可电切换元件。可采用全息光聚合物、HPDLC材料体系、均匀调制HPDLC材料体系或包含至少一个液晶和一个聚合物组分的任何其他材料体系形成光栅。材料或光栅特性可能会随阶跃变化而变化，也可能连续变化。为了传播不同波长带的图像光、不同角带宽的光和不同偏振的光，可对复用透射和反射光栅的规格进行优化。可以利用喷墨沉积工艺形成光栅。
图17从概念上显示了波导架构1700的轮廓图，其中，根据本发明实施例提供了重叠的透射1701和反射光栅1702、1703。在说明性实施例中，架构1700包括一个由基板1704、1705夹持的透射光栅1701，每个基板具有与反射光栅1702、1703其中之一接触的外表面。每个反射光栅的外表面与基板1706、1707接触。如图所示，在单独的层中设置透射光栅1701和反射光栅1702、1703。需要理解的是，光栅的全部或任何组合均可复用。如上所述，光栅可用于提供输入耦合、扩束和/或束提取。用光线1708示意性地表示光在波导中的传播。透射光栅K矢量(用符号K和数字1709A标记)为倾斜矢量。反射光栅布拉格条纹与用符号KR和数字1709B标记的K矢量基本上为不倾斜角度设置。用光线1710表示从波导中提取的光。
本质上，可将反射全息图视为分层折射率系统。在某些实施例中，可通过衰减引导射束在反射光栅的外层提供环境隔离，这样就可以在光到达波导的外表面之前发生大部分的全内反射。在某些实施例中，通过根据透射光栅和反射光栅的规格来建立补偿函数，来校正像差。反射全息光学元件(R-HOE)也可以实现弯波导。图18所示图表1800显示了本发明一个实施例中反射光栅1801的衍射效率与入射角的对比情况以及透射光栅1802的衍射效率角带宽。通常，反射光栅的衍射效率角带宽约为5-6°。在某些实施例中，HPDLC中记录的反射光栅可具有偏振选择性。在几个实施例中，上下反射光栅可具有对称的规格。
在某些实施例中，通过在透射光栅的上方和下方设置两个反射光栅来扩展波导的角带宽。图19从概念上显示了波导架构1900的轮廓图，其中，根据本发明实施例提供了重叠的透射光栅1901和反射光栅1902A、1902B、1903A和1903B。同样，尽管附图显示了在单独层中设置反射和透射光栅，但是光栅的所有或任何组合均可复用。在说明性实施例中，架构1900包括一个由基板1904、1905夹持的透射光栅1901，每个基板具有与反射光栅1902A、1903A其中之一接触的外表面。在上下两对光栅中，每对光栅的外反射光栅1902B、1903B外表面与基板1906、1907接触。用光线1908示意性地表示光在波导中的传播，用光线1909示意性地表示提取光。透射光栅K矢量(用符号K和数字1910A标记)为倾斜矢量，而反射光栅K矢量(用符号KR1和数字1910B以及符号KR2和数字1910C标记)基本上为不倾斜矢量。图20使用图表2000对反射光栅2001的衍射效率与入射角的对比情况、由两个反射光栅2002产生的有效角带宽以及透射光栅2003的衍射效率角带宽予以说明。
在一些实施例中，所述装置包括至少一个空间栅距变化的光栅。在某些实施例中，每个光栅具有一个固定的K矢量。在某些实施例中，至少一个光栅采用根据引用文献公开实施例和指导所述的滚动K矢量光栅。滚动K矢量允许扩展光栅的角带宽，而无需增加波导厚度。在某些实施例中，滚动K矢量光栅包括一个波导部分，所述波导部分包含以不同方式配向的K矢量的离散光栅元件。在某些实施例中，滚动K矢量光栅包括一个波导部分，所述波导部分包含一个单光栅元件，其中K矢量在方向上发生平滑的单调变化。在一些实施例中，利用所述滚动K矢量光栅将光输入到波导中。
在一些针对采用非偏振光源的显示器的实施例中，本发明中使用的输入光栅将各个光栅结合在一起，各个光栅的取向使得每个光栅将入射非偏振光的特定偏振衍射到波导路径中。在此类实施例中，可包含第PCT/GB2017/000040号PCT申请(“用于提供偏振选择性全息波导器件的方法和装置”)中公开的一些实施例和指导，所述PCT申请的公开内容通过本发明的整体引用，成为本发明的一部分。也可采用类似的方式配置输出光栅，因此来自波导路径的光经过结合后作为非偏振光从波导中耦合出来。例如，在一些实施例中，在正交偏振状态下，输入光栅和输出光栅分别与具有峰值衍射效率的交叉光栅相结合。在一些实施例中，偏振状态是指S偏振和P偏振。在某些实施例中，偏振状态与圆偏振的含义相反。在这一点上，液晶聚合物系统(如SBG)中记录的光栅的优势在于，由于自身固有的双折射，使这种光栅表现出很强的偏振选择性。然而，也可采用提供独特偏振状态的其他光栅技术。
在一些实施例中，使用液晶聚合物材料体系中记录的光栅，可提供与折叠光栅、输入光栅或输出光栅中至少一个光栅重叠的至少一个偏振控制层来对任何光栅(尤其是折叠光栅)中存在的偏振旋转予以补偿，发明人发现，所述情况可导致偏振旋转。在某些实施例中，所有光栅均被偏振控制层所覆盖。在一些实施例中，偏振控制层仅应用于折叠光栅或光栅的任何其他子集。偏振控制层可包括光学延迟器膜。在一些基于HPDLC材料的实施例中，光栅的双折射可用于控制波导器件的偏振特性。将HPDLC光栅的双折射张量、K矢量和光栅足迹作为设计变量，为优化波导器件的角度能力和光学效率开辟了设计空间。在某些实施例中，设置在波导玻璃-空气分界面上的四分之一波片使光线的偏振发生旋转，从而保持与光栅的高效耦合。例如，在一个实施例中，四分之一波片是一层涂覆在基板波导上的涂层。在一些波导显示器实施例中，将四分之一波片涂覆在波导的基板上，有助于通过补偿波导中的斜波，使光线始终与预期视轴配向。在某些实施例中，可作为多层覆盖层提供四分之一波片。
如各种示例性实施例所示，各系统和方法的构造和布置仅用于说明目的。本公开中仅详细描述了几个实施例，但是可以做出许多修改(例如，各种元件的大小、尺寸、结构、形状和比例，参数值、安装布置、材料的使用、颜色、取向等变化)。例如，元件的位置可以倒转或以其他方式变化，离散元件或位置的性质或数量可以改动或变化。因此，所有修改均纳入本公开的范围内。任何过程或方法步骤的次序或顺序均可根据替代实施例做出变化或重新排序。在不脱离本公开范围的情况下，可在示例性实施例的设计、运行条件和布置中做出其他替换、修改、变更和省略。
等同原则
尽管在上述说明中包含很多本发明具体的实施例，但是不应将所述实施例解释为对本发明范围的限制，而只应将其解释为本发明一个实施例的示例。因此，应当理解，除非特别说明之外，在不脱离本发明范围和精神的情况下，可采用多种方式实施本发明。因此，无论从哪方面来看，都应将本发明的实施例视为说明性实施例，而非限制性实施例。因此，本发明的范围不应由所示实施例决定，而应由所附权利要求及其等同内容决定。
