Effects of the Detection Efficiency on Multiplicity Distributions

, 2013
In this paper we investigate how a finite detection efficiency affects three popular multiplicity distributions, namely the Poisson, the Binomial and the Negative Binomial distributions.

Development of Detector System with Small Cell Multi-wire Drift Chamber

Yuanzineng kexue jishu
In order to accurately measure the path of the incident particles in front of the target at the CSR outer target terminal, multiple sets of small cell multi-wire drift chamber detectors were developed with a drift cell of 5 mm. The sensitive area of this

High efficiency compression for object detection

, 2018
Image and video compression has traditionally been tailored to human vision. However, modern applications such as visual analytics and surveillance rely on computers seeing and analyzing the images before (or instead of) humans.

Information capacity of direct detection optical transmission systems

, 2017
We show that the spectral efficiency of a direct detection transmission system is at most 1 bit/s/Hz less than the spectral efficiency of a system employing coherent detection with the same modulation format.

Necessary and sufficient detection efficiency for the Mermin inequalities

, 2008
We prove that the threshold detection efficiency for a loophole-free Bell experiment using an $n$-qubit Greenberger-Horne-Zeilinger state and the correlations appearing in the $n$-partite Mermin inequality is $n/(2n-2)$.

Experimental observation of nonclassical effects on single-photon detection rates [PDF]

, 2000
It is often asserted that quantum effects can be observed in coincidence detection rates or other correlations, but never in the rate of single-photon detection. We observe nonclassical interference in a singles rate, thanks to the intrinsic nonlinearity

Vision-Aided Hyperspectral Full-Waveform LiDAR System to Improve Detection Efficiency

Remote Sensing, 2023
The hyperspectral full-waveform LiDAR (HSL) system based on the supercontinuum laser can obtain spatial and spectral information of the target synchronously and outperform traditional LiDAR or imaging spectrometers in target classification and other ...

A single atom detector integrated on an atom chip: fabrication, characterization and application

, 2010
We describe a robust and reliable fluorescence detector for single atoms that is fully integrated into an atom chip. The detector allows spectrally and spatially selective detection of atoms, reaching a single atom detection efficiency of 66%.

The detection efficiency of on-axis short gamma ray burst optical afterglows triggered by aLIGO/Virgo [PDF]

, 2014
Assuming neutron star (NS) or neutron star/stellar-mass black hole (BH) mergers as progenitors of the short gamma ray bursts, we derive and demonstrate a simple analysis tool for modelling the efficiency of recovering on-axis optical afterglows triggered
