Abstract
Abstract State of the art micromirror DMD spatial light modulators (SLM) offer unprecedented frame rate of up to 32000 frames per second. This, in conjunction with fast digital camera, makes it possible to create high speed optical encryption systems. Experimental setup for optical encryption under spatially incoherent illumination based on two DMD SLMs had been created. Input information is displayed by first SLM, encoding hologram - by second SLM. Results of optical experiment demonstrate successful encryption and decryption of digital information in the form of QR code image.
