Three-Dimensional Object Recognition With Multiview Photon-Counting Sensing and Imaging
IEEE 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]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesThe 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
Entropy, 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 ...

Photon statistics in the macroscopic realm measured without photon-counters [PDF]
, 2009 In a macroscopic realm, in which photons are too many for being counted by any photon counting detector, photon statistics can be measured by using detectors simply endowed with linear response.

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

Coherent π^0 photoproduction on the deuteron up to 4 GeV [PDF]
, 1999 The differential cross section for ^2H(γ,d)π^0 has been measured at deuteron center-of-mass angles of 90° and 136°. This work reports the first data for this reaction above a photon energy of 1 GeV, and permits a test of the apparent constituent counting
