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 LIDAR device includes an input node, an output node, and a sample-and-convert circuit. The input node receives a photodetector signal, and the output node generates an output signal indicating a light intensity value of the photodetector signal. The sample-and-convert circuit includes a number of detection channels coupled in parallel between the input node and the output node. In some aspects, each of the detection channels may be configured to sample a value of the photodetector signal during the sample mode and to hold the sampled value during the convert mode using a single capacitor.
