Embodiment Construction

[0018] Such as figure 1 As shown, it includes an attitude control tool 1, a rotary platform 3, a mirror frame 8, an inner focusing telescope 5, a CCD camera 6, and a PC 7. The attitude control tool 1 is arranged on the rotary platform, and the mirror frame 8 is fixed on the top surface of the rotary platform. The inner focusing telescope is arranged directly above the picture frame and connected with the CCD camera; the CCD camera receives the image points observed by the inner focusing telescope, the other end of the CCD camera is connected with the PC, and the corner cube is fixed in the picture frame.

[0019] Look for the self-collimating image of the front face of the corner cube prism and the reflection (point reflection) image of the corner cube prism through the inner focusing telescope, rotate the high-precision rotary table and adjust its horizontal and pitch attitude so that the two images do not shake, and its optical axis It can be determined (the optical axis of ...

Abstract

The invention relates to a corner prism vertical type optical fixed axis system and method. The corner prism vertical type optical fixed axis system comprises a posture control tool, a rotary platform, an optical frame, an internal focusing telescope, a CCD camera and a PC. The posture control tool is arranged on the rotary platform. The optical frame is fixed on the top face of the rotary platform. The internal focusing telescope is arranged right above the optical frame and is connected with the CCD camera. The CCD camera receives image points observed by the internal focusing telescope. The other end of the CCD camera is connected with the PC. A corner prism is fixed in the optical fame. The invention aims at solving the technical problem of blank of an existing corner prism optical axis confirming method. The corner prism vertical type optical fixed axis system is simple in structure.

Description

technical field [0001] The invention belongs to the field of optical centering, and in particular relates to a method for vertical optical centering of a cube mirror. Background technique [0002] The corner cube prism (retroreflector) is an internal total reflection prism manufactured according to the principle of critical angle. It is not affected by the incident angle and reflects the incident light by 180°. That is to say, for any incident light entering the clear aperture, it will be efficiently reflected back in the original direction. This prism was used to find secret airfields as early as World War II. Instead of shooting light from the ground, the pilot just needs to mount a flash near his forehead, and the prism located on the airfield returns the beam the same way, thus discovering the airfield. In the Apollo (Apollo) space voyage, the corner cube prism had an important application. An array of more than 50 corner cube prisms is placed on the surface of the mo...
