Abstract
Computer simulations of the recording and reading of holograms in an 8-bit phase-code multiplexing system are presented. From the computer simulation each recording time of eight holograms is obtained such that the strength of restored holograms is same. An analytic formula to predict the recording times is derived by fitting the formula to the computer simulation data. It is found that our analytic formula can predict the hologram recording time not only in 8-bit system but also in 16-bit and 32-bit systems in an error less than $\pm$8.4%. Optical experiments are also performed in a 4-bit phase code-multiplexing system. It is found that the strength of the restored holograms is more uniform compared with conventional methods.
