Holographic information pertaining to an object can be generated using an active optical heterodyne scanning technique. In this technique, the holographic information manifests itself as an electrical signal which can be sent to an electron-beam-addressed spatial light modulator for coherent image reconstruction. Real-time holographic imaging of 2-D objects has recently been demonstrated. The use of alternate waveforms in the scanning beam can process the holographic content of the object in real time. In this communication, we propose a holographic edge extraction technique which utilizes alternate waveforms in the optical scanning holographic recording stage. We have developed a 1-D computer model of the optical heterodyne scanning holographic system using Fourier analysis which we use to simulate holographic edge extraction.
