Abstract
A Light Detection And Ranging (LIDAR) apparatus includes a pulsed light source to emit optical signals, a detector array comprising single-photon detectors to output respective detection signals indicating times of arrival of a plurality of photons incident thereon, and processing circuitry to receive the respective detection signals. The processing circuitry includes one or more of a recharge circuit configured to activate and deactivate subsets of the single photon detectors for respective strobe windows between pulses of the optical signals and at differing delays, a correlator circuit configured to output respective correlation signals representing detection of one or more of the photons having times of arrival within a predetermined correlation time relative to one another, and a time processing circuit comprising a counter circuit configured to increment a count value and a time integrator circuit configured to generate an integrated time value based on the respective correlation signals or detection signals.
