ABSTRACT

Combination of gyro north-finder, self-collimation photoelectric theodolite can be composed a ground rapid directional aiming system. In the paper, based on the CCD angle measurement technology, the self-collimation optical system is redesigned, focal length of the optical system is calculated, and the appropriate parameters are chosen. Optical conjugate design of the three light paths of light source module, visual module, and CCD receiving module is adopted to synchronize the transmission beams of the three light paths. The simulation and optimum design of light paths in the optical system are achieved by using the ZEMAX software. By analyzing the spot diagram and modulation transfer function (MTF), appropriate structural parameters of the optical system suitable for aiming working conditions are obtained.
