Paper Abstract

Real-time (video frame rate) optical correlation and wavelet transformation using high- resolution LCTV-SLMs and Fresnel zone plates have been studied. In the systems, the LCTV- SLMs are used as real-time optical filtering devices in Fourier planes and the Fresnel zone plates are used as Fourier transformation devices. In the experiment, good optical performance has been achieved. From the results, it is confirmed that the Fresnel zone plates are suitable devices for parallel optics and using them, they can be extended parallel optical systems easily.
