Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is described in detail, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained on the premise of not making creative work, broadly fall into the scope of this utility model protection.
Shown in ginseng Fig. 1, Salar light-gathering eyeglass focusing system, including condenser 1, light guide plate 2 and photographing unit 3, the summit of condenser 1 convex surface is fixed on level ground 5 by short pedestal 4, make the sufficiently close together ground of condenser 1, personnel adjust without relying on platform or lift to be implemented with minute surface focusing, complete focusing operation and can be greatly saved the activity duration from ground.
The concave surface array of condenser 1 is provided with multiple direct reflection sheet, light guide plate 2 and photographing unit 3 and is arranged at the surface of condenser 1, and is positioned on the centrage of condenser, and light guide plate 2 is made up of the little illuminating lamp that can individually be unlocked/close.Preferably, photographing unit 2 and light guide plate 3 are installed at 2 times of focal lengths of condenser.
The design of little illuminating lamp is to choose impact point on direct reflection sheet, because the design of direct reflection chip architecture is known, so it is known that the coordinate of impact point, according to the direct reflection sheet parabola equation of design, can calculate reflection light position on light guide plate, this position is exactly the installation site of little illuminating lamp, the number of little illuminating lamp, depend on that choosing of design point, every piece of direct reflection sheet can select 8 impact points, or more.
It is further fixed on bracing frame on the concave surface of condenser, along condenser centerline direction, the first fixture and the second fixture are installed on support frame as described above, being fixed with laser instrument on described first fixture, the central authorities of described second fixture offer the aperture passed for laser along centerline direction.
When opening laser, laser is launched by aperture, impinges upon on the camera lens of photographing unit, is used for adjusting light guide plate and fixes.
Focusing accuracy in order to ensure system direct reflection sheet, it is necessary to assure the relative position of photographing unit, light guide plate and the centrage of condenser.In the present embodiment, bracing frame being fixed with 2 fixtures 8, first fixture is placed in Stirling engine supporting construction, and its design should meet can enable the light beam from laser overlap with system centre line.Second fixture is arranged on Stirling engine mounting, and it has individual aperture in central authorities, and laser can extend there through.The height of the pitch-row engine framework on target is identical with electromotor receptor center.When laser through and laser beam will be made to overlap with the centrage of system during laser target sub-aperture.
System also includes the computer being connected to photographing unit and the printer being connected with computer, and light guide plate is connected with lamp controller, lamp controller control the unlatching/closedown of each little illuminating lamp.Little illuminating lamp is preferably LED.
In technique scheme, light guide plate is luminous by little illuminating lamp, light emits directive photographing unit from direct reflection sheet, photographing unit is for catching the image formation by rays that direct reflection sheet reflects, computer can be as lamp controller, order little illuminating lamp to open/close, and obtain the imaging of reflection light by being connected to photographing unit, process data so that it is determined that the normal of direct reflection sheet and angle.Printer is connected to computer, prints in order to the bolt adjustment amount after calculating.Laser instrument, fixture and calibration lamp are for making photographing unit be directed at the centrage of condenser.
