Abstract:We show that long depth of focus can be achieved with a pixelated lens (PL) encoded onto a reconfigurable spatial light modulator (SLM). Our PL has a phase distribution similar to that of a conventional axilens. Additionally, our resulting reconfigurable PL is employed in a novel shape recovering system. A feature of this system is that no moving parts or motors are required to scan a three-dimensional object. Numerical simulations and experimental results are shown.
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.
