Abstract
We consider a double random phase encoding Encryption/Decryption system in which the image
encryption/decryption process is performed numerically. In this paper we look at the effect of quantisation in the
decryption process due to the discrete values which a spatial light modulator can display. We look at the
characterisation of a transmissive spatial light modulator and we present results from simulations of the system.
