Abstract
Optical energy from a broadband source is focused on an aperture in an opaque member. The energy exiting the aperture is received off axis by a parabolic mirror which collimates the energy. The collimated energy is reflected from each planar mirror of an actuated mirror array. The reflected energy from the mirror array is re-reflected to the aperture by the parabolic mirror. The orientation of each planar mirror determines the flux which passes through the aperture or is reflected by a reflective face of the opaque member. The energy reflected from this face which is derived from each mirror corresponds to the flux intensity for a corresponding pixel. This energy may then be focused on a screen to display the scene.
