OPTICAL IMAGES SUPERPOSITION IN THE FRACTIONAL FOURIER TRANSFORM DOMAIN

摘要

The FFT images optical superposition regularities are investigated for the general case of two shifted and modulated by the plane wave optical signals. Principal possibility of the optical superposition of two images in the FFT domain at an arbitrary value of parameter p is theoretically proved. Numerical reults which demonstrate forming of the night-contrast interference band pattern in the FFT images optical superposition point are given. Domains of the FFT realization in the optical systems are investigated.
