The system is mainly used for examining the eye forepart tissue.
Description
Technical field
This utility model relates to the opticianry instrument field, is specifically related to a kind of tomography eye scanning system that moves.
Background technology
The following concrete defective of a tomography eye scanning system ubiquity of moving at present both domestic and external:
Generally adopt single cover to move a scanning lens and move camera shaft; Its image precision after computer is handled is still not high; Can't compare analysis in same angle position, can only carry out the interpolation match through interval angle picture shot and form, so the accuracy of check measurement is relatively poor relatively.
Like what announced on JIUYUE 15th, 2010; Publication number is that the Chinese invention patent of CN 101828900 A provides " a kind of tilt-shift fault scanning device "; Adopted and singly moved a camera technique, realized the rotation sweep function basically, but the defective of this patented technology on imaging precision still exists.In addition; In the characteristic of its claim 1 about the technical characterictic of " moving a light path of photography equipment " only recorded and narrated " move a light path of photography equipment ... be connected through wired mode between the external equipment "; Other technical characterictics about " moving a light path of photography equipment " have been documented in aforementioned part; And documents " patent No. is the United States Patent (USP) of US6286958 " according to its description and accompanying drawing and this patent; All significantly show it is a cover " moving a light path of photography equipment " and " video camera " of taking on the light path, so the defective of its poor accuracy certainly exists.
Do not see yet in the market and can overcome above defective, tilt-shift fault scanning system simple in structure, easy to assembly, that cost is lower, image quality is higher.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, and overcoming of never seeing on a kind of market is provided, and this defective, function are practical, a well behaved tomography eye scanning system that moves.
This utility model adopts with following technical proposals:
System comprises light source 1, crack diaphragm 2, projectoscope group 3, reflective device 4, eyes leading portion tissue 5, eyes 6, focusing mirror group 7, focusing camera 8, it is characterized in that,
Also be provided with a plurality of imaging shaft camera lens 9, a plurality of camera shafts 10 that move of moving;
The said same tangent plane that moves 9 pairs of said eyes leading portion tissues 5 of imaging shaft camera lens that moves camera shaft 10 and correspondence thereof of every cover can photographic images.
Every cover is said move camera shaft 10 and the corresponding same tangent plane photographic images that moves 9 pairs of said eyes leading portion tissues 5 of imaging shaft camera lens thereof after, can the anglec of rotation to next tangent plane photographic images of said eyes leading portion tissue 5.
When the said same tangent plane that moves 9 pairs of said eyes leading portion tissues 5 of imaging shaft camera lens that moves camera shaft 10 and correspondence thereof of many covers is taken, adopt the mode photographic images of synchronization exposure.
When the said same tangent plane that moves 9 pairs of said eyes leading portion tissues 5 of imaging shaft camera lens that moves camera shaft (10) and correspondence thereof of many covers is taken, adopt mode photographic images to the tow sides exposure of same tangent plane.
Preferably be provided with said camera shaft 10 and the corresponding said lens shaft 9 that moves thereof of moving of two covers.
Preferably, the said said lens shaft 9 that moves that moves camera shaft 10 and correspondence thereof of two covers organizes 5 formed primary optical axis to become axial symmetry to arrange along said reflective devices 4 and said eyes leading portion.
This utility model is compared with the contrast patent, and technical scheme is different, beneficial effect is different.Significant advantage of this utility model and beneficial effect are embodied in: overlap the said said lens shaft 9 that moves that moves camera shaft 10 and correspondence thereof more and take simultaneously; Make the picture that can photograph the positive and negative or more perspective of more or even same tangent plane in same angle; Computer can carry out the contrast compensation and the match computing of a plurality of pictures to each angle when handling these pictures; Can calculate effective picture of more approaching said eyes 6 practical situations, thereby significantly improve the accuracy that detects.
