Abstract
The fractional Fourier transform (FT) is a powerful tool with relevant applications in optical and digital information processing. Such applications demand a programmable and versatile optical system able to perform the fractional FT almost at real time. We have recently developed an optical setup satisfying these requirements. In contrast with other proposed setups, it offers the following advantages: the operation is achieved without additional scaling and/or phase factors and a minimal number of lenses, located at fixed position, are utilized.1 In this work we present the main design features of the fractional FT processor and discuss its performance for some relevant applications.
