What is Photon Counting Lidar Systems?

Photon Counting Lidar Systems use single-photon detectors like Geiger-mode APDs and SiPMs for direct-detection lidar enabling high-resolution 3D imaging at low light levels.

These systems employ time-correlated single-photon counting (TCSPC) for precise time-of-flight measurements in applications like bathymetry and altimetry. Key detectors include silicon photomultipliers (SiPMs) and single-photon avalanche diodes (SPADs) integrated in CMOS SoCs (Niclass et al., 2013; 193 citations; Bamji et al., 2014; 190 citations). Over 200 papers explore photon-efficient imaging and atmospheric correction algorithms (Shin et al., 2015; 224 citations).

Key Challenges

Why It Matters

Photon counting lidars enable eye-safe, space-based profiling for topography and ocean bathymetry using micropulse lasers at high repetition rates. Shin et al. (2015) demonstrate photon-efficient 3D imaging requiring few detections per pixel, vital for low-power satellite missions. Niclass et al. (2013) and Bamji et al. (2014) detail CMOS SoCs achieving 100m range and 512x424 resolution for automotive and Kinect applications. Gundacker and Heering (2020) highlight SiPM use in LIDAR distance measurements (212 citations).

Key Research Challenges

Sparse Photon Deconvolution

Algorithms must reconstruct high-resolution images from sparse photon detections amid Poisson noise. Shin et al. (2015) address this via computational imaging with single-photon detectors. Atmospheric scattering further distorts signals in long-range profiling.

Atmospheric Correction Algorithms

Multiple scattering in air and water requires precise correction for accurate bathymetry. Photon counting exacerbates signal sparsity in these conditions. Fossum and Hondongwa (2014) discuss pinned photodiode limits in noisy environments (430 citations).

Detector Afterpulsing and Crosstalk

SiPMs suffer from afterpulsing and optical crosstalk reducing single-photon resolution. Acerbi and Gundacker (2018) model these effects in SiPM simulations (289 citations). High repetition rates amplify these artifacts in lidar systems.
