Abstract
The theory of orthogonal wave-front coding for range information extraction from a single image in a passive way is introduced. A cosine rectangular separable optical mask was chose in the system. The expression of the diffractionlimited system's OTF for the value of defocus was deduced by method of the Ambiguity Function. The system's accuracy was analyzed using the Fisher information matrix and an evaluation of the Cramer-Rao bound. Simulation experiment results show the orthogonal method was feasible. An experimental system was also built, and results are given.
