Abstract
A method that records accurate information of an object beam is discussed. Before conducting our experiment, the effect of phase fluctuation was calculated using the coupled wave theory. Simulation results showed that the fringe amplitude decreased as the phase noise level increased. We propose a method for phase compensation even if a modulated object beam, which consists of black-and-white pixels, is used with a millisecond recording time. A recording experiment was conducted, in which even pages were without compensation and odd pages were with compensation with 100 angle multiplexing. The obtained results indicate that the mean brightness was increased by 2 ×105, and the mean error count for each page was reduced from 17 to 13 by improving the diffraction efficiency.
