Paper Abstract

In order to obtain a small spot size of the data-bearing signal beam with a uniform intensity distribution at the recording plane, we studied an image folding technique using a lenslet array. The use of such a signal beam may improve the area storage density in holographic memories with a disk-shape storage medium. Computer simulations show that our technique based on image folding can give better results than the defocusing method does both in the intensity uniformity of the signal beam and in the area storage density.
