Optical correlators are efficient optical systems that have gained a wide range of
applications both in image recognition and encryption, due to their special properties that …

A novel nonlinear encryption–decryption system based on a joint transform correlator (JTC)
and the Gyrator transform (GT) for the simultaneous encryption and decryption of multiple …

We present a first implementation of an optical encryption setup in the fractional Fourier
domain using an electrically focus-tunable lens. Fractional Fourier transform cryptosystems …

En esta contribución se discuten los avances más significativos en el campo de la
encriptación de información mediante procesamiento óptico con énfasis en los adelantos en …
