Abstract
In one embodiment, a lidar system includes a light source configured to emit (i) local-oscillator light and (ii) pulses of light. The lidar system also includes a receiver configured to detect the local-oscillator light and a received pulse of light, the received pulse of light including a portion of one of the emitted pulses of light scattered by a target located a distance from the lidar system. The receiver includes a detector configured to produce a photocurrent signal corresponding to a coherent mixing of the local-oscillator light and the received pulse of light. The detector includes a first input side and a second input side located opposite the first input side, where the received pulse of light is incident on the first input side of the detector, and the local-oscillator light is incident on the second input side of the detector.
