Optical Double Binary Amplitude Mask Structure for Security Authentication
A novel method for jointly designing two binary amplitude masks (BAMs) that allow for secure authentication is proposed. The speckle-noise diffraction pattern generated numerically from the input secret image encrypted by a random phase is binarized and further compressed. The resulting BAM can be s...
