Abstract

The construction of digital Fourier transform holograms by methods analogous to the optical Vander Lugt pro-cess, using a high-precision, multiple gray-level plotting source, is demonstrated. The theory of sampled holograms and the problems inherent in these digital methods are discussed, and calibration problems are explored. Finally, examples of the use of such holograms as spatial filter masks are presented.
