Abstract

In described examples, a system for outputting a patterned light beam includes a digital micro-mirror device having an array of micro-mirrors. Diffraction patterns displayed using the digital micro-mirror device create at least one patterned light beam in a field of view. An illumination source illuminates the array of micro-mirrors in the digital micro-mirror device. The system includes a processor coupled to provide display diffraction patterns for display using the digital micro-mirror device and to control the illumination source, and at least one detector to detect light from the patterned light beam that reflects from objects in the field of view.
