Abstract
A beam addressed electrostatically-actuated charge controlled mirror (CCM) with frame time utilization approaching 100% is provided by partially coating the CCM's pixelized beam addressing surface with a material having the opposite electron affinity. Each pixel of the pixelized beam addressing surface has first and second portions that exhibit secondary emission coefficients that are respectively less than and greater than one for the same beam energy. A beam or beams that are capable of subpixel resolution selectively address each pixel's first and second portions to control the amount of charge on the pixelized beam addressing surface and its localized potentials.
