Abstract
A LiDAR system includes an array of optical emitters, an objective lens optically coupling each optical emitter to a respective unique portion of a field of view, an optical switching network coupled between a laser and the array of optical emitters and a controller coupled to the optical switching network and configured to cause the optical switching network to route light from the laser to a sequence of the optical emitters according to a dynamically varying temporal pattern and to vary the temporal pattern based at least in part on distance to an object within the field of view. The LiDAR system scans different portions of the field of view differently, such as with different laser power levels, different revisit rates and/or different scan patterns, for example based on likelihood of detecting objects of interest in the various portions or based on likely relative importance of objects likely to be found in the various portions.
