TL;DR: A scanning time-of-flight system which uses the time-correlated single-photon counting technique to produce three-dimensional depth images of distant, noncooperative surfaces when these targets are illuminated by a kHz to MHz repetition rate pulsed laser source.

TL;DR: By using a scanning transceiver which incorporated a free-running, low noise superconducting nanowire single-photon detector, this paper was able to obtain centimeter resolution depth images of low-signature objects in daylight at stand-off distances of the order of one kilometer at the relatively eye-safe wavelength of 1560 nm.

TL;DR: An InGaAs/InP single-photon avalanche diode detector module in conjunction with a time-of-flight depth imager operating at a wavelength of 1550 nm, is used to acquire centimeter resolution depth images of low signature objects at stand-off distances of up to one kilometer.

TL;DR: A depth imaging system, based on the time-of-flight and time-correlated single-photon counting (TCSPC) technique, was investigated for use in highly scattering underwater environments and a LiDAR model was developed and validated using experimental data.

TL;DR: In this article, the first demonstration of superconducting nanowire single-photon detectors (SNSPDs) for 1O2 luminescence detection was reported, with a fibre-coupled cavity-enhanced SNSPD with >20% practical detection efficiency at ~1300 nm, representing a 20-fold improvement in efficiency over NIR PMTs used to date for singlet oxygen luminecence dosimetry.
