Phase-only optical encryption |
|
| Authors: | Mogensen P C Glückstad J |
| Abstract: | 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. |
