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.

Multiple LIDAR output signals are generated and are concurrently directed to the same sample region in a field of view. The LIDAR output signals have one or more optical diversities selected from a group consisting of wavelength diversity, polarization diversity, and diversity of an angle of incidence of the LIDAR output signal relative to the sample region.

The LIDAR system includes a polarization component configured such that a first light signal traveling through the polarization component along an optical pathway has its polarization angle changed from a first polarization angle to a second polarization angle. The polarization angle is also configured such that a second light signal traveling the optical pathway in a direction that is the reverse of the direction traveled by the first light signal both enters and exits the polarization component in the second polarization angle. The LIDAR system is configured to output a LIDAR output signal that includes light from the first light signal. The LIDAR system is also configured to receive a LIDAR return signal that includes light from the LIDAR output signal after the LIDAR output signal was reflected by an object located outside of the LIDAR assembly.
