Abstract

Single photon sensitive 3D imaging lidars have multiple advantages relative to conventional multiphoton lidars. They are the most efficient 3D imagers possible since each range measurement requires only one detected photon as opposed to hundreds or thousands in conventional laser pulse time of flight (TOF) or waveform altimeters. Their high efficiency enables orders of magnitude more imaging capability (e.g. higher spatial resolution, larger swaths and greater areal coverage). In our Single Photon Lidars (SPLs), single photon sensitivity is combined with nanosecond recovery times and a multistop timing capability, This enables our lidars to penetrate semiporous obscurations such as vegetation, ground fog, thin clouds, etc. Furthermore, the 532 nm operating wavelength is highly transmissive in water, thereby permitting shallow water bathymetry and 3D underwater imaging.
