Abstract

A fully optical encryption system based on the single-phase encryption method is presented. A two-dimensional array of real-valued data is phase encoded and scrambled with a random phase key for encryption. The encrypted data is stored holographically in a DuPont photopolymer, and is reconstructed by conjugate readout. The original data can be retrieved using a same phase key for decryption and an interferometer for phase-to-intensity conversion. The influence of a limited bandwidth on the bit-error-rate in the decrypted data is evaluated. With binary data, error-free decryption can be possible even when a large fraction of encrypted data is lost.
