Example embodiments relate to light detection and ranging (lidar) devices having a light-guide manifold. An example lidar device includes a transmit subsystem. The transmit subsystem includes a light emitter. The transmit subsystem also includes a light-guide manifold optically coupled to the light emitter. Further, the transmit subsystem includes a telecentric lens assembly optically coupled to the light-guide manifold. The lidar device also includes a receive subsystem. The receive subsystem includes the telecentric lens assembly. The receive subsystem also includes an aperture plate having an aperture defined therein. The aperture plate is positioned at a focal plane of the telecentric lens assembly. Further, the receive subsystem includes a silicon photomultiplier (SiPM) positioned to receive light traveling through the aperture.

Light detection and ranging (lidar) device having a light-guide manifold

A display may have a backlight unit that provides backlight illumination. The backlight unit may include a light guide that distributes light through the display. Light-emitting diodes may emit light into the light guide. A reflector that is overlapped by the light guide may help reflect light upwards through an array of pixels. The backlight unit may have a chassis that receives the reflector, light guide, light-emitting diodes, and optical films such as diffusers and prism films. Optical and mechanical features in the backlight unit may enhance color and intensity uniformity for the backlight illumination and may help enhance durability.
