Abstract: A spatial light modulator (SLM) has an array of pixels configured to modulate light in patterns responsive to first control signals. The modulated light forms at least one patterned light beam in a field of view. An illumination source is optically coupled to the SLM. The illumination source is configured to illuminate the array of pixels, responsive to second control signals. Circuitry is coupled to the SLM and to the illumination source. The circuitry is configured to provide the first control signals to the SLM and the second control signals to the illumination source. At least one detector is configured to detect a reflection of the patterned light beam in the field of view.

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: Described examples a three-dimensional printer includes a vat having a transparent bottom, the vat configured to contain a photo-polymerizing resin and a lift plate movably positioned within the vat. The three-dimensional printer also includes an optical device configured to project a pattern of light through the transparent bottom. The optical device includes a light source configured to provide light at a light source output and a light integrator configured to provide divergent light at a light integrator output responsive to the light at the light source output. The optical device also includes projection optics configured to project projection output light at an optics output through the transparent bottom responsive to a modulated light at the optics input and a spatial light modulator configured to provide the modulated light responsive to the divergent light.

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.
