Optical energy from a broadband source (12) is focused on an aperture (30) in an opaque member (16). The energy exiting the aperture (30) is received off axis by a parabolic mirror (18) which collimates the energy. The collimated energy is reflected from each planar mirror of an actuated mirror array (20). The reflected energy from the mirror array (20) is reflected to the aper- ture (30) by the parabolic mirror (18). The orientation of each planar mirror determines the flux which passes through the aper- ture (30) or is reflected by a reflective face (28) of the opaque member (16). The energy reflected from this face (28) which is de- rived from each mirror corresponds to the flux intensity for a corresponding pixel. This energy may then be focused on a screen (24) to display the scene.
