Abstract: A lidar system having a lidar transmitter and lidar receiver that are in a bistatic arrangement with each other can be deployed in a climate-controlled compartment of a vehicle to reduce the exposure of the lidar system to harsher elements so it can operate in more advantageous environments with regards to factors such as temperature, moisture, etc. In an example embodiment, the bistatic lidar system can be connected to or incorporated within a rear view mirror assembly of a vehicle.

Abstract: A lidar receiver that includes a photodetector circuit can be controlled so that the detection intervals used by the lidar receiver to detect returns from fired laser pulse shots are closely controlled. Such control over the detection intervals used by the lidar receiver allows for close coordination between a lidar transmitter and the lidar receiver where the lidar receiver is able to adapt to variable shot intervals of the lidar transmitter (including periods of high rate firing as well as periods of low rate firing). The lidar receiver can define the detection intervals based on a region in the field of view that a laser pulse shot is targeting (e.g., setting longer detection intervals for laser pulse shots targeting a horizon region, setting shorter detection intervals for laser pulse shots targeting a region that intersects within the ground within a relatively short distance of the lidar system).

Abstract: A lidar system that includes a laser source can be controlled to schedule the firing of laser pulse shots at range points in a field of view. As part of this scheduling, the system can prioritize which elevations will be targeted with shots before other elevations based on defined criteria. Examples of such criteria can include prioritizing elevations corresponding to a horizon, prioritizing elevations which contain objects of interest (e.g., nearby objects, fast moving objects, objects heading toward the lidar system, etc).
