Abstract:Abstract:In order to best assess the importance of new technologies to optical design, it is useful to consider what the limits are to what can be done with ' old ' technologies. That may show where something new is needed to overcome the limitations of existing optical designs. This article will give a survey of some remarkable highperformance designs, some of which are extremely simple, and most of which only use technology that has already been around for decades. Each of these designs has some limitation t… 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.
