Optical encryption of series of images using a set of encryption keys using scheme operating with spatially-incoherent illumination based on two LC SLMs

Optical encryption and numerical decryption of series of test images using a set of different encryption keys is carried out using scheme operating with spatially-incoherent illumination based on two LC SLMs. Results of experiments on images optical encryption and numerical decryption are presented. Satisfactory average decryption error over 49 encrypted images equal to 0.20±0.05 is achieved.
