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/

Simulation of Target Tracking based on Photon-counting Laser Ranging System

open access: yesGuangtongxin yanjiu, 2022
As the single photon detection greatly improves the sensitivity of a traditional detector, it has enormous potentiality in distance measuring. Photon-counting laser ranging is able to extract the target's trajectory from large amounts of echo information

A Photon Imaging Detector Model with High Resolution and High Counting Rate

open access: yesApplied Sciences, 2023
A cross strip (XS) anode detector is a photon-counting imaging detector with high spatial resolution. However, due to the Poisson distribution characteristics of the photons emitted by the target, photons with a small time interval will cause signal ...

Characterize the Speed of a Photon-Number-Resolving Superconducting Nanowire Detector

open access: yesIEEE Photonics Journal, 2020
Superconducting series nanowire single-photon detectors (SNDs) have been used for resolving photon numbers. But it can also exhibit a higher counting rate than a single superconducting nanowire single-photon detector (SNSPD), because the serial ...

Tantalum STJ for Photon Counting Detectors [PDF]

open access: yesIEEE Transactions on Appiled Superconductivity, 2005
Superconducting Tunnel Junctions (STJ's) are currently being developed as photon detectors for a wide range of applications. Interest comes from their ability to cumulate photon counting with chromaticity (i.e. energy resolution) from the near infrared (2 $μ$m) to the X-rays wavelengths and good quantum efficiency up to 80%.
