Real-time coherent correlator using binary magnetooptic spatial light modulators at input and Fourier planes
Abstract
The present study is concerned with an experimental correlator which uses the Light-Mod magnetooptic spatial light modulator (SLM) devices for real-time modulation of both input images and Fourier plane filters. The results obtained in a demonstration are in good agreement with computer simulations based on the FFT. The results presented demonstrate the potential for useful real-time correlation systems based on the employment of binary magnetooptic SLMs. It is pointed out that in some cases it may be preferable to use a gray scale (or analog response) SLM for the input device.
