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: In described examples, a spatial light modulator (SLM) receives light from a field of view. The SLM includes a two-dimensional array of picture elements in rows and columns. In response to a transmit scan beam that illuminates the field of view, a portion of the two-dimensional array is impacted by light reflected from a region of interest. The portion of the two-dimensional array is determined. Light is directed from the portion of the two-dimensional array to a photodiode. Light that impacts the two-dimensional array outside the portion is directed away from the photodiode.

Abstract: In an example, a system includes a digital micromirror device (DMD). The DMD includes a hinge and one or more spring tips coupled to the hinge, where the hinge is configured to tilt toward a raised address electrode. The DMD includes a micromirror including a recessed mirror shelf and a reflective surface, where the recessed mirror shelf is coupled to the hinge, and where the recessed mirror shelf is configured to contact at least one of the one or more spring tips responsive to the hinge tilting toward the raised address electrode.

Abstract: A method of aligning optical signals in a fiber optic switching device with one or two phase light modulators (PLMs) includes configuring the phase elements of the PLMs with first initial settings, to direct an optical signal from an input fiber to an output fiber. An initial position displacement of a center of the signal image from a center of the output fiber is estimated. Corrected settings for the phase elements are calculated so that when the corrected settings are applied to the phase elements, a corrected signal image of the optical signal has a corrected position displacement from the center of the output fiber that is less than the initial position displacement. A fiber optic switching device has processing circuitry and a memory component configured to execute steps of the method of aligning the optical signals.

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 (e.g., a microelectromechanical system) includes a substrate, a support coupled to the substrate and a first and second element. The first element includes a contactor spring having a first portion coupled to the support and having a second portion including a cavity having a sloped surface. A clearance from the sloped surface to the substrate is widened as the sloped surface extends away from the first portion. The second portion includes a first contact surface adjacent to the sloped surface. The second element is coupled to the substrate and has a second contact surface adjacent to the first contact surface. One of the first element and the second element is adapted: in a first direction to urge the first contact surface and the second contact surface together; and in a second direction to urge the first contact surface and the second contact surface apart.
