Experimental set-up. A diode pump laser (DPL) source illuminates a high-speed DMD, on which rapidly changing binary patterns are displayed. These patterns are projected by a 50 mm camera lens to illuminate a printed United States Air Force (USAF) resolution chart, which was located at a distance of ~0.5 m from the camera lens. A lens collects the reflected light, and the intensity is measured by a quadrant PIN detector. An analogue-to-digital converter (ADC), synchronized with the DMD, acquires and transfers the measured data to a computer for image reconstruction.
