Sažetak
In this paper quantization influence on digital hologram reconstruction is presented. Digital hologram is constructed using composition of spherical waves applied over simple 2D binary images. Three different quantization approaches were used before reconstruction of given hologram. The first approach directly reconstructs hologram (without quantization), the second approach quantifies given hologram on two levels (black and white hologram) and the third approach quantify given hologram on 256 levels (greyscale hologram). After applied quantization, hologram is reconstructed and each reconstructed image is compared with original 2D binary image. Given results showed significant quantization influence on digital hologram reconstruction.
