US Patent 11686845 Hyper temporal lidar with controllable detection intervals based on regions of interest

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).
