摘要
Holographic optical elements for Fourier transform (HOE-FT) used in the optical memory system are considered in this paper. The determination of the optimal page composer capacity allows for the appropriate choice of the diameter of HOE-FT as well as the size of a hologram recorded in the fotorefractive crystal LiNbO3:Fe, with the help of two different wavelengths of the laser light beam. When the interfering field is recorded in the HOE-FT structures, properties of the recorded spectrum are established. The proper choice of the phase function coefficients allows aberration to be corrected on the basis of spotdiagrams obtained.
