Abstract
Image hiding based on optical time-averaging moiré technique is presented in this paper. It is a new visual decoding scheme when the secret image is embedded into a moiré grating and can be interpreted by a naked eye only when the image is harmonically oscillated in a predefined direction. The secret image is visualized at strictly defined amplitude of oscillation. Computational and experimental examples are used to demonstrate the functionality of the method.
