Abstract

In this paper, we propose a new angular multiplexing method for storage of the image in BaTiO₃. To perform the angular multiplexing, a SA (simulated annealing) algorithm and a LCTV (liquid crystal television) are used. The SA algorithm is used to design a BPH (binary phase hologram) for reference beam generation, and the LCTV is used to modulate the phase. Reference beam is generated by a Fourier transforming of the phase hologram on the LCTV which is controlled by the computer to record and read images in real time. Recording time of each image is determined by scheduled recording method for uniform diffraction efficiency. Through an optical experiment, we show that four images are recorded and reconstructed by the proposed angular multiplexing method.
