Paper Abstract

The past several years have seen a dramatic increase in the application of electro-optical techniques to the problems of mechanical alignment. Although these problems have existed for a long time, the applications are new and have required significant developments in position sensing detectors. UDT's lateral effect photodiodes and the systems using them represent state-of-the-art in position sensing. The discussion will include physics of these position sensing detectors and the presently available specifications.
