A sensitivity modulated light detection and ranging (LIDAR) system and related methods. Implementations of sensitivity modulated LIDAR systems may include a pulsed laser and a light detection system coupled with the pulsed laser through a timing system. The light detection system may include a high-bandwidth detector coupled with the timing system, at least one imaging detector coupled with the timing system, and at least one sensitivity modulator coupled with the at least one imaging detector and with the timing system.
