Abstract

The variety of ways in which optical techniques are now being applied to information processing problems will be reviewed and compared. Information to be processed is sometimes in optical or image form, i.e., image processing; in this case, optics is essential, at least for the input/output phase. Emphasis is placed on the problems of information storage by optical and photographic means. Also, optics has been used to good advantage for certain analog processing problems.
