摘要：

This study describes optical encryption based on joint transform correlator architectures using a binary phase difference key mask, designed by discrete sine function interpolation. The key mask has the required properties of space-limited and phase-mostly spectrum for accurate image recovery. Gray-level image encryption and decryption performance measures are discussed as well.
