Paper Abstract

This paper analyzes the noise caused by the quantization effects of computer generated holograms (CGHs). To utilize a fabrication that is compatible with VLSI processing techniques, a CGH having only two levels of phase is fabricated. The binarization not only reduces the maximum efficiency of CGH but also causes some optical noise which may lead to signal crosstalk. The maximum deflection angle of CGH is determined by the smallest written spot of the hardware. The divergence angle of semiconductor laser signal transmitter causes a decrease of the maximum deflection angle of the CGH. Here we present a way of increasing the maximum deflection angle by using the divergence angle of a semiconductor laser.
