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.

Abstract: An optical distance measuring system includes a first transmitter, a first solid state device, and a receiver. The first transmitter is configured to generate a first optical waveform. The first solid state device is configured to receive the first optical waveform and steer the first optical waveform toward a target object. The receiver is configured to receive the first optical waveform reflected off of the first target object and determine a distance to the first target object based on a time of flight from the transmitter to the first target object and back to the receiver.

Abstract: A spatial light modulator outputs modulated light including: modulated first light when the spatial light modulator receives first light; and modulated second light when the spatial light modulator receives second light. Projection optics project the modulated light onto: a first pixel region when a component or the spatial light modulator has a first position; and a second pixel region when the component or the spatial light modulator has a second position. The first and second pixel regions partially overlap. A pixel shifter moves the component or the spatial light modulator between: the first position when the spatial light modulator outputs the modulated first light; and the second position when the spatial light modulator outputs the modulated second light.

Abstract: Described examples include an optical device, having a light source with a light source output and a light integrator having a light integrator input and a light integrator output, the light integrator input optically coupled to the light source output, and the light integrator configured to provide divergent light at the light integrator output responsive to the light at the light source output. The optical device also has projection optics with an optics input and an optics output, the projection optics configured to project output light at the optics output responsive to modulated light at the optics input, in which a focal point of the optics input matches a divergence of the modulated light and a spatial light modulator optically coupled between the light integrator output and the optics input, the spatial light modulator configured to provide the modulated light responsive to the divergent light.
