Description
Technical field
This utility model relates to the opticianry instrument field, is specifically related to a kind of eye imaging device.
Background technology
The optical instrument that detects or take a picture to eye at present; Generally comprise illumination path and observation light path; Illumination path is used for illuminating the person's of being observed eyes; Its light that reflects shines on observer's the eye or observation device through the observation light path again, to be used to observe and take the health status that eyes comprise the optical fundus.
But because patient's eye complex structure; Concrete physiological tissue situation is also varied; Especially optical instrument is used for observing and when taking pictures; Cornea and the unnecessary reflected light that connects an objective lens surface etc. be through can forming ghost under a lot of situation behind the optical instrument, thereby reduced the overall image quality of observing and taking, therefore with regard to necessary ghost and the various veiling glare in whole Optical devices, eliminated.
Existing eye image optics instrument adopts the way of stain plate or annular diaphragm to eliminate ghost and veiling glare more, and specifically, there is following defective in these devices:
1. can not eliminate ghost and veiling glare fully, the picture quality that obtains is still relatively poor.
2. illumination path is independent respectively with the observation light path, and cost is higher.
3. eliminate the optical texture relative complex of ghost and veiling glare, volume ratio is huger.
4. when adopting annular diaphragm, the light source utilization rate is lower, and energy consumption is relatively large.
5. the luminous flux that gets into patient's ophthalmic is more, causes prescription on individual diagnosis person's ophthalmic uncomfortable easily.
Do not see yet in the market and overcome above defective, image quality is higher, structure is simple relatively, cost is low, less energy consumption and to the imaging device of the little elimination ghost better effects if of patient's eye side effect.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, provide never see on a kind of market can overcome these defectives, practical, the well behaved eye imaging device of function.
This utility model adopts following technical scheme:
The device of this utility model is by light source module 101, spectral module 102, common optical pathways module 103, eyes 104, optical fundus 105, picture receiver 106; Light source power supply module 201, picture receiver driver module 202, control treatment display module 203, motion driver module 204 are formed, and said picture receiver 106 can be an area array sensor.Its creationary summary of the invention is that said motion driver module 204 connects and drive the radial motion of said light source module said light source module 101 in 101 edges and said spectral module 102 formed upper reaches illumination paths; Simultaneously said picture receiver 106 is along radially continuously the window exposure of said spectral module 102 with said picture receiver 106 formed downstream observation light paths; Windowing continuously of said picture receiver 106 read the synchronized movement of signal and said light source module 101.
A kind of optical arrangement is: the light that said light source module 101 sends is after said spectral module 102 reflections; Scan through 103 pairs of said eyes 104 of said common optical pathways module again; The light that reflects is through after the said common optical pathways module 103; After said spectral module 102 refractions, arrive said picture receiver 106, said picture receiver 106 all or part of exposures again.
Another kind of optical arrangement is: the light that said light source module 101 sends is after said spectral module 102 refractions; Scan through 103 pairs of said eyes 104 of said common optical pathways module again; The light that reflects is through after the said common optical pathways module 103; After said spectral module 102 reflections, arrive said picture receiver 106, said picture receiver 106 all or part of exposures again.
Said picture receiver 106 carries out signal and is connected with said picture receiver driver module 202, control treatment display module 203 orders; The electronic signal information that said control treatment display module 203 can splice the said core exposure area 200 that said picture receiver driver module 202 transmits is all or part of with the eyes image 300 that forms bigger zone, and handles, writes down or show.
The motion of said light source module 101 preferably can be a uniform motion, so that realization is even to the illuminating effect of said eyes 104, all even imaging effect of exposure effect is even.The motion of said light source module 101 can be unidirectional once motion, also can be to move back and forth.Said motion driver module 204 carries out signal with said control treatment display module 203 and is connected, and said control treatment display module 203 can be controlled the motion that said motion driver module 204 removes to drive said light source module 101.
Wherein, said light source module 101 is comprising on the basis of light source device, can also all or part ofly comprise condenser lens group, light balancing device, illumination diaphragm.The emergent ray of said light source module 101 preferably can form band light source.Said spectral module 102 can be an Amici prism, also can be plane beam splitter, to reflect by a certain percentage and transmitted ray.Said common optical pathways module 103 can comprise the projectoscope group and connect an object lens.
The light that preferably said light source module 101 sends can scan irradiation through the said optical fundus 105 of said spectral module 102,103 pairs of said eyes 104 of common optical pathways module.
After this utility model adopted new innovative technology scheme, through test, it was less to reflect back in the light of said picture receiver spare 106 veiling glare, is difficult to form ghost again.
Its significant advantage and beneficial effect specifically also are embodied in the following aspects:
1. because adopted the light source module that moves; The penlight scanning so be achieved, thus can utilize narrow slit to eliminate unnecessary light to temporarily the do not make public irradiation at position of eyes, start with from the source; Eliminate possible unnecessary veiling glare, can obtain good observation and photographic images.
2. because picture receiver has adopted the Exposure mode of windowing continuously; Switching signal is read in penlight exposure and small core zone so be achieved; Thereby when further having eliminated light and in the device of forming through optical instrument and eyes, having propagated; Various diffuse-reflectance, the formed unnecessary veiling glare of directional error have further guaranteed picture quality.
3. illumination and observation imaging optical path are on succinct as far as possible common optical pathways, to realize.
4. used optics is less, is easy to realize that cost is lower.
5. control is simple, and departure is less.
6. the light that needs can be less, so the power consumption of light source also can obtain the reduction of certain amplitude with dispelling the heat.
7. can use band light source to throw light on as patient's eye, the luminous flux that gets into patient's eye is less, can reduce the stimulation of light to patient's eye in a large number, makes the patient comparatively comfortable when inspection, and the patient is easy to adapt to.
