The vertical optical axis positioning system for the pyramid prism has a simple structure.
Description
Technical field
The utility model belongs to the optical centering field, is specifically related to the vertical optics dead axle of a kind of pyramid mirror system.
Background technology
Prism of corner cube (retroreflecting device) is a kind of inner full-reflection prism of manufacturing according to the critical angle principle, and it is not subject to the impact of incident angle size, 180 ° of incident light reflections.In other words, for arbitrary incident ray that enters clear aperature, all will by former direction, be reflected back efficiently.Early just apply during World War II this prism and find secret airport.The pilot, as long as load onto a flashlamp and need to not shoot out from ground light near his forehead, is positioned at the prism An Yuan road Returning beam on airport, thereby finds airport.In Apollo (Apollo) space travel, prism of corner cube has important application.Place the array of 50 above prism of corner cubes on moonscape, then the astronomer is high-power laser beam directive prism array, then receives and return the light beam of penetrating with telescope.Laser beam, through the twice stroke to the moon by the earth, approximately needs time 2.8s, can accurately calculate the distance of the earth to the moon thus.
Prism of corner cube is more and more applied, but but there is no a kind of method that can determine the optical axis of prism of corner cube, affects the service precision of prism of corner cube.
Summary of the invention
Determine the technical matters of method blank for existing prism of corner cube optical axis, the utility model provides the vertical optics dead axle of a kind of prism of corner cube system.
Technical solution of the present utility model:
The vertical optics dead axle of prism of corner cube system, its special character is: comprise attitude adjustment frock, revolving dial, picture frame, internal focusing telescope, light source, CCD camera and PC,
Described attitude is adjusted frock and is arranged on revolving dial, the center of described revolving dial is provided with light source hole, and described light source is arranged in light source hole, and described picture frame is fixed on the end face of revolving dial, described internal focusing telescope be arranged on picture frame directly over, with the CCD camera, be connected; Described CCD camera receives the picture point of internal focusing telescope, and the other end of described CCD camera and PC joint angle cone prism are fixed in picture frame.
The utility model has advantages of:
1, the vertical optics dead axle of prism of corner cube of the present utility model system, simple in structure.
2, the utility model adopts the optical non-contact metering system fully, find the end face of prism of corner cube and the reflection picture point on summit, change the spatial attitude of prism of corner cube by horizontal adjusting mechanism and aligning elevation gear, control the jerk value of two picture points in internal focusing telescope, guarantee the registration accuracy of optical axis and revolving dial revolving shaft.
The accompanying drawing explanation
The structural representation that Fig. 1 is the vertical optics dead axle of prism of corner cube of the present utility model system;
Wherein Reference numeral is: the 1-attitude is adjusted frock, 3-revolving dial, 4-prism of corner cube, 5-internal focusing telescope, 6-CCD camera, 7-PC machine, 8-picture frame, 9-power supply, 10-light source.
Embodiment
Find prism of corner cube front end face autocollimatic reflection image and prism of corner cube summit transmission picture by internal focusing telescope, the rotation high-precision rotary working-table is also adjusted attitude and is adjusted frock two picture points are not all rocked, and its optical axis can be determined (now prism of corner cube optical axis and high-precision rotary working-table center superposition)
Concrete steps: 1. internal focusing telescope is accommodated to the position, infinite distance, search out the autocollimation reflection image of prism of corner cube end face; 2. internal focusing telescope is accommodated to the prism of corner cube vertex position again, open light source simultaneously, find the summit transmission picture point of prism of corner cube, light source is exactly the summit transmission picture point of prism of corner cube through imaging point after prism of corner cube; 3. adjust by attitude level and the pitch attitude that frock is adjusted high-precision rotary working-table, control the rolling momentum of two picture points, 2 pictures are not rocked; 4. now the optical axis of prism of corner cube can be determined, the centre of gyration of the optical axis of prism of corner cube and high-precision rotary working-table overlaps.
Claims (1)
1. the vertical optics dead axle of prism of corner cube system is characterized in that: comprise that attitude adjusts frock, revolving dial, picture frame, internal focusing telescope, light source, CCD camera and PC,
Described attitude is adjusted frock and is arranged on revolving dial, the center of described revolving dial is provided with light source hole, and described light source is arranged in light source hole, and described picture frame is fixed on the end face of revolving dial, described internal focusing telescope be arranged on picture frame directly over, with the CCD camera, be connected; Described CCD camera receives the picture point of internal focusing telescope, and the other end of described CCD camera and PC joint angle cone prism are fixed in picture frame.
