Abstract
A new and simple image encryption scheme and optical decoding technique are presented based on the principle of interference. An original image is encoded into two phase-valued images. The interference image between the two images produces a binary image, which has a two-level intensity value. The performance of the proposed technique is evaluated using computer simulations and optical experiments
