Abstract
An optical system may be formed by including a plurality of discrete protrusions comprising electro-optic material. Each discrete protrusion is electrically and optically isolated from each other. The protrusions further have defined a top face, a bottom face, a first side face or first and second side faces, and front and back faces. A plurality of electrodes are associated with each of the protrusions. The electrodes are capable of inducing an electric field in the electro-optic material for independently modulating one or more light beams which are incident upon one of the faces of the protrusions. In one preferred embodiment, the protrusions are oriented with respect to the one or more light beams such that each of the light beams enters the protrusion and strikes a boundary between first and second portions of the protrusion at an angle and is reflected by total internal reflection when the first portion is electro-optically activated by application of sufficient voltage, but which will pass substantially unreflected through the boundary when the first portion is not electro-optically activated.
