Abstract

Anew architecture is described, for the real-time implementation of any discrete transform with incoherent light. Matrix-matrix products are performed using two 1-D acoustooptic spatial modulators with time-integration on a CCD camera. The operation can be iterated for N-D transforms, such as in multisensors image processing.
