Hyper Temporal Lidar with Shot Scheduling for Variable Amplitude Scan Mirror

A lidar system that includes a laser source and transmits laser pulses produced by the laser source toward range points in a field of view via a mirror that scans through a plurality of scan angles can use (1) a laser energy model to model the available energy in the laser source over time and (2) a...

More Information
Summary:A lidar system that includes a laser source and transmits laser pulses produced by the laser source toward range points in a field of view via a mirror that scans through a plurality of scan angles can use (1) a laser energy model to model the available energy in the laser source over time and (2) a mirror motion model to model motion of the mirror over time. The mirror can exhibit a variable scan amplitude, and a control circuit can then evaluate whether benefits such as a shorter completion time for firing laser pulse shots at a list of range points can be achieved by changing the mirror's scan amplitude. When making such decisions, the control circuit can take into account a settle time for the variable amplitude mirror that arises from changing the mirror's scan amplitude.
