Single-photon LIDAR operating in the short-wave infrared (SWIR) offers great potential for kilometre range three-dimensional imaging with improved penetration through atmospheric obscurants. The use of SWIR single-photon imaging provides an eye-safe technique with superior surface-to-surface resolution compared to alternative LIDAR approaches. We present two optical configurations for imaging in highly attenuating environments, such as fog. Three-dimensional target profiles were obtained in high levels of scattering media, and for targets hidden behind camouflage netting at ranges of hundreds of metres. Bespoke algorithms allow for sparse photon data reconstruction using short acquisition times, and for real time reconstruction of dynamic complex scenes.
