Alignment and detecting of photoelectric theodolite system through utilizing interferometer

Wang Yifan

Tracking accuracy and other technical criteria increasing leads to improving of alignment and detecting technology in optical system photoelectric theodolite. A new method of alignment and detecting for photoelectric theodolite main mirror, including assembling, adjustment, coating, axis detection and checking was introduced in this paper. Then, ZYGO interferometer was used in main mirror detecting, this method toke the place of traditional detecting method. Ultimately, ZYGO interferometer technology got clear image both from aviation aircraft 70-80 km away and target in the distant of 5 000 m according to the field experiments. The main mirror meets accuracy of designing and alignment. So the application of interferometer in photoelectric theodolite primary mirror enhances the alignment accuracy.
