Abstract

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 results which demonstrate forming of the height-contrast interference band pattern in the FFT images optical superposition point are given. Domains of the FFT realization in the optical systems are investigated.
