Description
Summary:The possibility of using a digital micromirror device (DMD) for implementing the optical encryption with time integration in quasimonochromatic spatially incoherent light is considered. An experimental setup for optical registration of image to be encrypted on a digital camera is presented. Images containing text and graphic information are encrypted and successfully decrypted using inverse filtering. The use of time integration in optical encryption makes it possible to reduce the noise caused by binarization of holograms display on DMD that contains encryption keys and to increase the diffraction efficiency of the encryption process.
