    摘要: A lidar system comprising (1) a first lens having a first field of view (FOV) that receives incident light from the first FOV, (2) a second lens having a second FOV that receives incident light from the second FOV, wherein the second field of view is encompassed by and narrower than the first FOV, and (3) photodetector circuitry that senses incident light passed by the first and second lenses. The photodetector circuitry can include multiple channels of readout circuitry for reading out (1) a first return signal in a first of the channels for detecting a return from a laser pulse shot that targets a location in the second FOV, wherein the first return signal is based on incident light passed by the first lens, and (2) a second return signal in a second of the channels for detecting the return, wherein the second return signal is based on incident light passed by the second lens.

    摘要: 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.

    摘要: 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.
