We investigate the depth imaging of objects through various densities of different obscurants
(water fog, glycol-based vapor, and incendiary smoke) using a time-correlated single-photon …

We present and discuss the case for full waveform pixel and image acquisition and
processing to enable LiDAR sensors to penetrate and reconstruct 3D surface maps through …

Abstract Single-Photon Avalanche Detector (SPAD) arrays are a rapidly emerging
technology. These multi-pixel sensors have single-photon sensitivities and pico-second …

The ability to measure and record high-resolution depth images at long stand-off distances
is important for a wide range of applications, including connected and automotive vehicles …

The challenges of real world applications of the laser detection and ranging (Lidar) three-
dimensional (3-D) imaging require specialized algorithms. In this paper, a new …

Stand-off detection and characterization of scattering media such as fog and aerosols is an
important task in environmental monitoring and related applications. We present, for the first …

Time-of-flight Lidars based on single-photon avalanche diode (SPAD) detector arrays are
emerging as a strong candidate technology for long range three-dimensional imaging in …

Single-Photon Avalanche Detector (SPAD) arrays are a rapidly emerging technology. These
multi-pixel sensors have single-photon sensitivities and pico-second temporal resolutions …

Fog is a difficult medium to image through using Single-Photon Avalanche Diode (SPAD)
based Light Detection and Ranging (LiDAR) systems because of its light scattering …

Ranging and imaging in low light level conditions are a key application of active imaging
systems. Typically, intensified cameras (ICCD, EBCMOS) are used to sense the intensity of …
