Paper Abstract

We compress the range of the gray level to obtain the phase modulation from 0 to 2 (pi) . We generate the kinoform using the iterative method that includes the phase and the cross couple amplitude modulation characteristics of the LCTV. As a result we obtain good quality on-axis reconstructed images. We find the random phase errors on the LCTV pixels that causes speckle noise on the reconstructed images. Optical experimental results are shown.
