Abstract

Optical passive ranging is based on the light signal radiated by the object itself. The application of wave front coding technology to passive ranging systems simplifies the system structure and improves the ranging accuracy to a large extent. In this paper, the orthogonal coding passive ranging system with the cosine form of the mask function is investigated, and the optical transfer function and the light intensity distribution at the distances of 1m-4m and 1km-5km are simulated by numerical simulation to verify the rationality of the orthogonal coding ranging system, and the measurement error is about. ±0.1m.
