In this paper, a dual-flexure pixel design is proposed to maintain well-defined diffraction nodes at or near the projection aperture edges over the full modulation range, achieving high image contrast.
Abstract
A spatial light modulator pixel includes a flexible reflective surface that is electrostatically actuated to control the surface shape and thereby phase-modulate reflected light. The reflected light is filtered by a projection aperture, wherein the phase modulation controls the amount of light from the pixel that is filtered through the aperture. The spatial light modulator includes and array of such pixels, which are imaged onto a conjugate image plane, and each pixel controls the image brightness at a corresponding conjugate image point. High image contrast is achieved by using a dual-flexure pixel design in which two flexure elements operate conjunctively to maintain well-defined diffraction nodes at or near the projection aperture edges over the full modulation range.
