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 proce… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
