Abstract :
We present a novel and simple cascaded acousto-optic image processing system to perform image processing. The system consists of two imaging lenses and two acousto-optic modulators that are placed in series. Real time image processing is achieved by Bragg diffraction. Computer simulation is given and compared to an optical image processing system which uses a single acousto-optic modulator
