Abstract
A deformable mirror light valve includes a plurality of substantially transparent parallel electrodes which are disposed on one surface of a transparent substrate. The electrodes are electrically insulated from each other. A photoconductor layer is on the transparent electrodes and an elastomer layer is on the photoconductor layer. A deformable mirror is on the elastomer layer. The plurality of electrodes permit the biasing voltage for each area on the light valve to be optimally phased with respect to the scanning of that area. Consequently, the use of this device provides for a substantially uniform deformation intensity, i.e., read out intensity, over the entire area of the light valve.
