In this paper a new simple image encryption scheme and an optical decoding technique based on the principle of interference are proposed. An original image is encoded into a reference image and an encrypted image. The reference image is randomly generated, and the encrypted image is gotten by the encryption rule based on the principle of interference. These images have phase-only information and consist of two phase values `0' or `(pi) '. The interference image between two images becomes a binary image, which has a two-level intensity value. The performance of the proposed technique is evaluated using computer simulations and optical experiments.
