Abstract
Quality deterioration of reconstructed 3-D images in the electro-holography is discussed. Effects of the bit-depth limitation in quantization, of the phase shift of light caused by the amplitude modulation, and of the amplitude limitation are studied by the numerical simulation. Comparison of optically reconstructed images with numerically reconstructed images shows that the nonlinear characteristics of a LCD panel and the phase shift of light due to the amplitude modulation have significant influences upon the quality of reconstructed images. Especially, the contrast of optically reconstructed images becomes remarkably low. New methods are described for improving the quality of reconstructed images in the experiment. The nonlinear characteristics of the LCD panel and the phase shift of the modulated light can be made correction by data processing in the electro-holography.
