Abstract: A device for image gating using an array of reflective elements is provided herein. The device includes an array of reflective elements, wherein each one of the reflective elements is movable within a range of a plurality of tilt positions, wherein the array is located at an image plane of the device, wherein the array is perpendicular to an optical axis of the device. The device further includes a control unit configured to control the reflective elements such that in at least some of the tilt positions, the reflective elements reflect the radiant flux at said image plane, to one or more projection planes. A gradual rotation of the reflective elements along the plurality of tilt positions result in a gradual increase or decrease in the intensity of the image reflected from the array of reflective elements while maintaining the image integrity.
