Paper Abstract

The purpose of this paper is to study the sampling and quantization effects on the hologram for communication purposes, and evaluate the system performance while considering the appearance of the different types of noises: (1) nonlinearity, (2) sampling effect, (3) additive noise, and (4) quantization noise. A technique for modeling the experimental holographic system, especially on the behavior of the hologram, is proposed. First, we analyze the linear and nonlinear holographic systems and simulate their performances. Therefore, the nonlinear effects on the hologram are studied. Simulation is provided to verify the theoretical results shown here. It is found that the linear hologram is more preferable than the nonlinear hologram in performance, although the nonlinear hologram has a better utilization of light efficiency. The downsampled hologram will reduce the light-use efficiency and thus the system performance is degraded. Moreover, the additive channel and quantization noise effects on the hologram are studied. For examples: the amplitude of the additive noise must be less than 1/100 of the average power per pixel of the hologram during the exposure; an 8-bit quantizer is necessary to transmit the digitized holographic signals. With the results obtained here, a holographic system can be designed efficiently.
