摘要：

All-optical image coding and decoding is demonstrated for the encipherment. The optical parallel coder consists of two cascaded bipolar-operational spatial light modulators (BSLM's) that can select positive and negative image readout in response to the electrical pulse polarity. Coding is performed by exclusive-OR operation to a key and an input image, while decoding is the same operation to a decoding key and an enciphered image.
