Abstract
An exemplary system includes an array of photodetectors and a control system. Each photodetector of the array of photodetectors may include a single-photon avalanche diode (SPAD) and a fast-gating circuit configured to arm and disarm the SPAD. The control system is configured to control a current drawn by the array of photodetectors.
