title: Simple phase-only optical decryption with misalignment-free input.
abstract: An improved optical decryption system based on kinogram encoding is proposed. The decrypted phase image is obtained by optically descrambling the encrypted image with the decrypting phase key. Only a single Fourier lens is needed to generate intensity patterns from the decrypted phase image. The design and simulation results have confirmed the proposed technique as a novel, simple, and robust decryption architecture.
