US Patent 11460552 Hyper temporal lidar with dynamic control of variable energy laser source

A lidar system that includes a variable energy laser source and transmits laser pulses produced by the variable energy laser source toward range points in a field of view can use a laser energy model to model the available energy in the variable energy laser source over time. The timing schedule for laser pulses fired by the lidar system can then be determined using energies that are predicted for the different scheduled laser pulse shots based on the laser energy model. This permits the lidar system to reliably ensure at a highly granular level that each laser pulse shot has sufficient energy to meet operational needs, including when operating during periods of high density/high resolution laser pulse firing. The laser energy model is capable of modeling a variable rate of energy buildup in the variable energy laser source per unit time.
