ABSTRACT:
An apparatus and method for capturing an image, using a spatial light modulator (SLM) 11 and a single-element sensor 15. The SLM 11 is an array of individually switchable pixel elements, which reflect light toward the sensor if switched to an "on" position. As each pixel element is switched on, light from that pixel element is directed to the sensor 15. For each pixel element, the sensor 15 generates a signal proportional to the light associated with that pixel element, the result being a series of signals representing at least one image frame. The process may be repeated for a number of image frames for generating moving pictures.
