摘要：
We have implemented a phase-only optical encryption and decryption system with a readout based on the generalized phase-contrast method. The experimental system has been implemented with Liquid-crystal spatial light modulators to generate binary phase-encrypted masks and a decrypting key. A phase-contrast filter is used to display the phase information. (C) 2000 Optical Society of America. OCIS codes: 230.6120, 230.3720, 120.5060, 100.1160, 100.5090, 070.2580.
