Abstract
To solve depth of field issues when scanning, transmitting, and receiving light pulses in a lidar system, a receiver in the lidar system may include a lens having a lens plane in front of one or several photodetectors arranged on a detector plane. The lens plane and the detector plane may be nonparallel with respect to each other creating a wedge shaped depth of field. In this manner, return light pulses from far away and nearby targets may stay in focus.
