Abstract: An example projector includes: a first light source to provide first light; and a second light source to provide second light. A spatial light modulator produces: first modulated light by modulating the first light; and second modulated light by modulating the second light. An image direction device directs: the first modulated light to project a first image having a first pixel position; and the second modulated light to project a second image having a second pixel position.

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 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: A projector includes a laser light source and a glass wheel. The laser source is configured to generate laser light. The glass wheel is optically coupled to the laser source. The glass wheel includes a first surface and a second surface. The first surface is configured to receive the laser light, and includes a light direction device optically coupled to the laser source. The second surface is opposite the first surface and is configured to emit light. The second surface includes a first arc of a phosphor deposited at a first distance from a center of the glass wheel. The light direction device is configured to direct the laser light to the first arc of the phosphor. The second surface also includes a second arc of the phosphor deposited at a second distance from the center of the glass wheel.

Abstract: In described examples, a body includes an opening in a central portion of a surface, a cavity having sides extending from the opening into the body, and a bottom surface within the body supporting a phosphor configured to emit light when energized by incoming light. In a further arrangement, the sides are tapered from the opening to the bottom surface, such that a cross sectional area of the opening is greater than a cross sectional area of the bottom surface.

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 include a device includes a first post and a spring supported by the first post. The device also includes a second post coupled to the spring and a mirror on the second post. Additionally, the device includes a movable layer coupled to the spring and to the mirror and a fixed layer, where the movable layer is between the fixed layer and the mirror. The mirror has a width and a length and the length is greater than the width. The mirror is configured to move based on a voltage difference between the movable layer and the fixed layer.
