We review the progress achieved in optical information processing during the last decade by applying fractional linear integral transforms. The fractional Fourier transform and its applications for phase retrieval, beam characterization, space-variant pattern recognition, adaptive filter design, encryption, watermarking, and so forth is discussed in detail. A general algorithm for the fractiona...

Optical computing and optical neural network have gained increasing attention in recent years because of their potential advantages parallel processing at the speed light low power consumption by comparison with electronic computing. The implementation fundamental building blocks a digital computer, i.e. logic gates, has been investigated extensively past few decades. gate is an alternative app...
