Abstract
An optical Gabor coefficient evaluation scheme for transient signals is proposed. With an acousto-optic modulator as an input device, a liquid-crystal spatial light modulator as a reconfigurable window, and a two-dimensional charge-coupled-device detector array, a real-time optical processing architecture that determines the Gabor coefficients of transient signals is described. Some preliminary experimental results are presented.Keywords
