Abstract:Angular Domain Imaging (ADI) is a technique that selects quasi-ballistic photons exiting from a highly scattering medium by an array of silicon micromachined micro-tunnels. Each channel has a limited acceptance angle based on its geometry therefore those photons that traverse within the acceptance angle of the micro-tunnels will be detected by the imager. In this paper, the ADI technique has been investigated by using newly micromachined tunnels with less spacing between the channels. Also, a Keplerian lens sy… 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.
