The multimode interferometer is configured to provide a second optical output signal to a second optical channel coupled to a second output port of the multimode interferometer, and to provide a first optical output signal to a first optical channel coupled to a first output port of the multimode interferometer. Each of the first optical channel and the second optical channel is configured to emit light to an outside of the light detection and ranging system, and wherein the multimode interferometer is configured to generate a frequency difference between the first optical output signal and the second optical output signal.

摘要： Techniques for imaging such as lidar imaging are described where a plurality of light steering optical elements are moved (such as rotated) to align different light steering optical elements with (1) an optical path of emitted optical signals at different times and/or (2) an optical path of optical returns from the optical signals to an optical sensor at different times. Each light steering optical element corresponds to a zone within the field of view and provides (1) steering of the emitted optical signals incident thereon into its corresponding zone and/or (2) steering of the optical returns from its corresponding zone to the optical sensor so that movement of the light steering optical elements causes the imaging system to step through the zones on a zone-by-zone basis according to which of the light steering optical elements becomes aligned with the optical path of the emitted optical signals and/or the optical path of the optical returns over time.

摘要： In one embodiment, a lidar system includes a light source configured to emit pulses of light, where each emitted pulse of light includes a spectral signature of multiple different spectral signatures. The lidar system also includes a receiver configured to detect a received pulse of light, the received pulse of light including light from one of the emitted pulses of light scattered by a target located a distance from the lidar system. The emitted pulse of light includes one of the spectral signatures. The receiver includes a detector configured to produce a photocurrent signal corresponding to the received pulse of light, a frequency-detection circuit configured to determine, based on the photocurrent signal, a spectral signature of the received pulse of light, and a pulse-detection circuit configured to determine, based on the photocurrent signal, a time-of-arrival of the received pulse of light.
