Abstract: An optical distance measuring system includes a transmitter, a beam steering device, and a receiver. The transmitter is configured to generate a first plurality of optical waveforms. The beam steering device is configured to steer the first plurality of optical waveforms to a first plurality of scan points that form a non-uniform scan region within a field of view (FOV). The receiver is configured to receive the first plurality of optical waveforms reflected off of a first plurality of target objects within the non-uniform scan region and determine a distance to each target object of the first plurality of target objects based on a time of flight from the transmitter to each target object of the first plurality of target objects and back to the receiver.

Abstract: An apparatus includes a spatial light modulator (SLM) having a first region and a second region and a phase light modulator (PLM) optically coupled to the SLM. The PLM is configured to receive first light having a first color and receive second light having a second color, the second color different than the first color. The PLM is also configured to direct the first light towards the first region of the SLM and direct the second light towards the second region of the SLM.

Abstract: A digital micromirror device comprises an array of micromirror pixels, the array comprising a first micromirror pixel and a second micromirror pixel. The first micromirror pixel comprises a hinge, where the hinge is configured to tilt toward a first raised address electrode and toward a second raised address electrode. The first micromirror pixel also comprises a first micromirror coupled to the hinge, where the first micromirror has a sculpted edge. The second micromirror pixel comprises a second micromirror, where a first gap between a first point on the sculpted edge and a nearest point to the first point on the second micromirror is larger than a second gap between a second point on the sculpted edge and a nearest point to the second point on the second micromirror.

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 device includes at least one processor configured to partition a source image including image components into sub-images, each including a corresponding image component of the image components, and process each sub-image to produce a target image to be projected for each sub-image of the sub-images. The device also includes one or more light sources coupled to the at least one processor and configured to project an incident light, and a phase projection-based display device coupled to the at least one processor and optically coupled to the one or more light sources and configured to modulate, based on the target image of each sub-image, the incident light to separately project the sub-images.

Abstract: An apparatus includes a focusing lens, a SLM optically coupled to the focusing lens and comprising micromirrors on a surface of the SLM, where the focusing lens is tilted at an incident angle relative to the surface of the SLM, an incident light beam is illuminated on the SLM at the incident angle, and the incident angle is greater by an offset angle than twice a tilt angle of the micromirrors with respect to the surface of the SLM. The apparatus also include an actuator optically coupled to the SLM, and projection optics optically coupled to the actuator.

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.
