Abstract

Holographic Transformation (HT) of a black-white bitmap image was successfully realized using the free transferring principles of light and the principle of computer generated holography. The original image was successfully reconstructed on the computer. The possibility of using HT for image encryption in image communication is experimentally analyzed and testified. It is shown that five parameters in transformation and their sequence can be taken as the key to regenerate the original image, thus a certain degree security is realized.
