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: Described examples include apparatus having a driving electrode on a substrate. The apparatus has a platform suspended above the driving electrode and conductively coupled to a platform electrode, where the platform is configured to move in a direction perpendicular to a surface of the substrate in response to a voltage difference applied between the driving electrode and the platform electrode. The apparatus also has a mirror post on the platform. The apparatus has a mirror coupled to the platform by the mirror post, where the mirror is rectangular.

Abstract: In described examples, a system (e.g., a projection system) can include a diffractive optical element adapted to be illuminated by at least one coherent light beam. A lens array is coupled to receive a diffracted beam of light from the diffractive optical element. The lens array includes a first and a second array lens. The first array lens is coupled to receive a first sector of a pattern of illumination of the diffracted beam of light, and the second array lens is coupled to receive a second sector of the pattern of illumination of the diffracted beam of light. A spatial light modulator is coupled to receive overlapping diffracted beams of light from the first and second array lenses to form an image beam.

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.
