1. A light scrambling system comprising:
a substrate; and
at least one refractive index boundary formed by at least one discontinuity in the substrate;
wherein the substrate is adapted to receive a light input at a plurality of input locations and to transmit the light output though the substrate to a plurality of output locations;
wherein the input locations have a first spatial relationship to one another, wherein the output locations have a second spatial relationship to one another, and wherein the first spatial relationship is different from the second spatial relationship thereby scrambling the light received at the input locations and transmitted to the output locations.
