Abstract
The method to design an input phase mask for the double-random phase-encoding optical encryption is proposed. The input phase mask is designed so that the extend of the Fourier spectrum of the product of an input image and the input phase mask corresponds to the space bandwidth of the optical system. By using the designed input phase mask, we show that the bit-error rate is improved.
