Optical systems for imaging activated pixels of a linear cantilever beam light valve (14) on a receptor or screen (24) are disclosed. The systems include a light source (12), a condenser lens (16) and pupil mask (26) forming a beam (32) from the output of the light source (12), a relay lens (18) for the beam (32) to image the pupil mask (26) onto the linear cantilever beam light valve (14), and an imaging lens (22) with an optional iris diaphragm (50) for imaging the portion of the beam (32) reflected from activated pixels of the light valve (14) onto the receptor or screen (24) while blocking the portion of the beam (32) reflected or diffracted from the remainder of the light valve (14).
