“…The variations in this beam current represent the encoded optical image. A complete description of this process is available in the literature (6). In principle this type of detector possesses some real advantages.…”
A swept electron beam rapid scan spectrophotometer has been built in this laboratory. This device utilizes techniques which were originally intended for video applications.

“…The most popular video camera tube called Vidicon was developed in the 1950s by P.K. Weimer and his colleagues in U.S. electronic company RCA [7] as shown in Fig 2 . The input light from a scene passes through a lens system and hits the face plate made of glass. The light from the face plate falls on the so called target plate which has two layers.…”
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.
