Optical axis adjustment for multiple field TV Sight

In order to realize optical axis parallelism and stability adjustment for multiple field TV sight, an adjustment program combining the CCD target surface with the dual optical wedges was described, according to the structure of the opto-mechanical system. Through the design and establishment for the alignment device of which the mounting surface paralleled the optical axis, the uniform alignment benchmark was built with collimator auto-collimation method. Meanwhile, through the analysis of the principle of dual wedges, the adjustment program was optimized, the progress requirements of dual wedges pairing and coarse error control were added. The adjustment and test results show that the optical axis parallel accuracy is up to 0.1 mrad, and the optical axis stability accuracy is up to 0.05 mrad.
