Optical Image Encryption Using Devil’s Vortex Toroidal Lens in the Fresnel Transform Domain
We have carried out a study of optical image encryption in the Fresnel transform (FrT) domain, using a random phase mask (RPM) in the input plane and a phase mask based on devil’s vortex toroidal lens (DVTL) in the frequency plane. The original images are recovered from their corresponding encrypted...
