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).

Abstract: A lidar system that includes a laser source can be controlled to fire laser pulse shots from the laser source at a variable rate of firing those laser pulse shots. The fired laser pulse shots can include scheduled laser pulse shots that are targeted at range points in the field of view. The fired laser pulse shots can also include marker shots that bleed energy out of the laser source in order to avoid reaching a threshold for available energy in the laser source and/or regulate energy amounts for the targeted laser pulse shots. A laser energy model that models how much energy is available from the laser source for laser pulse shots over time can be used to model future available energies for the laser source and determine whether any marker shots should be fired.

Abstract: A lidar receiver can employ multiple processors to distribute the workload of processing returns from laser pulse shots. Activation/deactivation times of pixel sets that are used by the lidar receiver to sense returns can be used to define which samples in a return buffer will be used for processing to detect each return, and multiple processors can share the workload of processing these samples in an effort to improve the latency of return detection

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).

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 determine the detection intervals using a cost function that optimizes determination of the detection intervals for a plurality of the laser pulse shots from a shot list.

Abstract: A lidar system that includes a laser source and a scannable mirror can be controlled to schedule the firing of laser pulse shots at range points in a field of view. A first mirror motion model can be used to govern the scheduling of the laser pulse shots, and a second mirror motion model can be used to govern when firing commands are to be generated for the scheduled laser pulse shots. The first and second mirror motion models model motion of the scannable mirror over time. A system controller can use the first mirror motion model as a coarse mirror motion model for the purpose of shot scheduling, while a beam scanner controller can use the second mirror motion model as a fine mirror motion model for the purposes of generating firing commands for the laser source.

Abstract: A lidar system that includes a laser source and a scannable mirror can be controlled to fire laser pulse shots from the laser source toward targeted range points via the scannable mirror at a variable rate of firing those laser pulse shots. A control circuit for the lidar system can determine a shot order of the targeted laser pulse shots for the variable rate firing based on a plurality of simulations of different shot order candidates with respect to a laser energy model that models how much energy is available from the laser source for laser pulse shots over time as compared to a plurality of energy requirements for the targeted laser pulse shots. Parallelized logic resource in the control circuit can be used to perform the simulations in parallel to support low latency shot scheduling.

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 can employ multiple readout channels that are capable of simultaneously reading out sensed signals from different pixel sets of a photodetector array in order to detect different returns from different laser pulse shots. In doing so, the lidar receiver can support the use of overlapping detection intervals when collecting signal data for detecting the different returns from the different laser pulse shots.
