Abstract

The wavelength selectivity of the hologram using the reference beams with random phase codes and multiple wavelengths is calculated and compared with experimental results. If the angle between signal and reference beams goes to 180 degrees, the effect of random phase code does not significantly affect the wavelength selectivity. Cross-talk noise analysis is Fourier holographic memory using random phase codes and multiple wavelengths is performed, and the signal-to-noise ratio is shown to depend on the angle between signal and reference beams as well as the wavelength difference.
