Three-Dimensional Object Recognition With Multiview Photon-Counting Sensing and Imaging

open access: yesIEEE Photonics Journal, 2009
We present a method for photon-counting sensing with three-dimensional (3-D) integral imaging for object recognition using independent component analysis (ICA). A lenslet array is used to capture multiple perspective images of a 3-D scene projected onto

Study on Single Photon Imaging Method for Permanent Shadow Crater of the Moon [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The detection of the permanent shadow area of the moon is currently a research hotspot. As the name suggests, there is no light in the permanent shadow area, and traditional methods cannot image it. This paper proposes a single photon imaging method that

An Entropy-Based Anti-Noise Method for Reducing Ranging Error in Photon Counting Lidar

open access: yesEntropy, 2021
Photon counting lidar for long-range detection faces the problem of declining ranging performance caused by background noise. Current anti-noise methods are not robust enough in the case of weak signal and strong background noise, resulting in poor ...

Evaluation and Improvement of Lidar Performance Based on Temporal and Spatial Variance Calculation

open access: yesApplied Sciences, 2019
Poisson distributions have the characteristic of equality between their variance and mean values. By constructing a calculation model of the temporal variance and spatial variance, the relationship between the variance and mean values of lidar analog ...

Effect of Deep-Level Defects on the Performance of CdZnTe Photon Counting Detectors

open access: yesSensors, 2020
The effect of deep-level defects is a key issue for the applications of CdZnTe high-flux photon counting devices of X-ray irradiations. However, the major trap energy levels and their quantitive relationship with the device’s performance are not yet ...

Single-Pixel Photon-Counting Imaging Based on Dual-Comb Interferometry

open access: yesNanomaterials, 2021
We propose and experimentally demonstrate single-pixel photon counting imaging based on dual-comb interferometry at 1550 nm. Different from traditional dual-comb imaging, this approach enables imaging at the photon-counting regime by using single-photon ...

Single-Photon Counting Detectors

open access: yesIEEE Photonics Journal, 2011
Various new developments for array detectors based on Silicon Single-Photon Avalanche Diodes (SPADs) were reported. Improved Si-SPAD technologies brought higher detection efficiency in the red wavelength range. Higher performance was attained with InGaAs/
