Abstract: A depth imaging system includes an optical image sensor, an optical beam steering system, an object identification system, and a depth measurement system. The object identification system is coupled to the optical image sensor. The object identification system is configured to identify an object in an image captured by the optical image sensor. The depth measurement system is coupled to the optical beam steering device. The depth measurement system is configured to, responsive to identification of the object by the object identification system: direct an optical signal, via the optical beam steering device, to the object, and to determine a distance to the object based on a time-of-flight of the optical signal.

Abstract: A headlamp includes a digital micromirror device (DMD) reflector, a light source, and projection optics. The DMD reflector includes a DMD and a static reflector disposed on a plurality of sides of the DMD. The light source is disposed to illuminate the DMD reflector. The projection optics are configured to project light reflected by the DMD and light reflected by the static reflector via a same lens system.

Abstract: An illumination apparatus is provided that includes a yellow phosphor converter to receive a blue laser light beam and to convert a portion of the blue laser light beam to yellow light, a dichroic mirror optically coupled to the yellow phosphor converter to receive the phosphor-emitted light beam and to filter the phosphor-emitted light beam to provide a dichroic-filtered light beam, the dichroic mirror configured to pass yellow light and to reflect at least some blue light, and a blue light source optically coupled to the dichroic mirror to provide a blue light beam, the dichroic mirror configured to reflect the blue light beam in a same direction as the dichroic-filtered light beam.
