Abstract

Aiming at the problems of traditional wavefront coding system, such as single phase mask (modulation) and limited extended depth of field, a wavefront coding imaging system using deformable mirror (DM) is proposed to realize dynamic coding. In this paper, continuous pure phase coding based on Zernike polynomial is designed by the simulated annealing algorithm for different defocus distances, with the aim of thus getting the most suitable coding strength for different defocus distance. And in the decoding process, the PSF of the defocused position corresponding to the blurred image is used for restoration, which reduces the artifacts caused by using the PSF of the focal position to restore all the defocused images. The experiment shows that compared with the traditional fixed phase mask, the wavefront coding imaging system of DM can achieve dynamic coding and decoding, which increases the imaging flexibility of the wavefront coding system and improves the quality of the decoded image.
