Analytical description of the FFT realization in the nonideal optical schemes is given. The cases of single and double optical stages are considered and the domain of the FFT images forming is analysed. Based on signal distribution method input signal rotation on the informational diagram is explained. The FFT optical schemes analysis is carried out. Experimental results of the two shifted and modulated by the plane wave slits images superposition in the FFT domain are presented.
