摘要：
We proprose an experimental demonstration for the phase-only optical decryption based on kinogram encoding. Only one spatial light modulator is used to simtaneously display the encrypted information and the decrypting key for decryption. We investigate the effect of binary and multiphase keys on the security level of the encrypted information. The accepted displacement of the decryption key within the system is also determined. The free misalignment of the Fourier lens is experimentally demonstrated.
