Paper Abstract

Fourier transformation is a basic operation in many signal processing applications. A new optical processing approach that is capable of performing in real time cosine and sine transformations on the intensity distribution of an incoherent one-dimensional optical input is introduced. An optical configuration utilizing an achromatic grating interferometer to implement the processing approach is presented. This versatile processing system can be configured to perform operations currently being accomplished by other special purpose optical processors. In addition, it can be used to process signal received directly from incoherent scenes without going through any transducer.
