Optical Image Encryption With Divergent Illumination and Asymmetric Keys
A flexible optical encryption system based on divergent illumination and asymmetric encoding is proposed. The input image is encrypted by use of two random phase masks (RPMs) located at the input and the conjugate plane in a diverging spherical wave field. Compared with the counterparts using planar...
