Problems solved by technology

The computing resources occupied by this coincidence calculation management method will increase in a factorial manner when the number of channels changes linearly, which will accelerate the consumption of system computing resources, resulting in the system being unable to provide redundant calculations for coincidence counting when the number of channels reaches a certain value. resources, resulting in a significant reduction in the counting efficiency of the system

Abstract

A coincidence-counting management method and device are provided. The method comprises the following steps of: receiving a coincidence counting indication instruction and analyzing the coincidence counting indication instruction to obtain a plurality of counting combinations and channel data of each counting combination; according to the channel data of each counting combination, judging whether there is a combination inclusion relationship among the counting combinations, and a plurality of counting combinations in which there is a combination inclusion relationship being divided into the same counting strategy, obtaining photon generation time data of each optical channel corresponding to each counting strategy, and controlling the corresponding thread of the counting strategy to performcoincidence counting on each optical channel corresponding to the counting strategy based on the preset time window width and the corresponding photon generation time data in the time period corresponding to the preset counting time length. The method can save system computational resources, improve coincidence counting efficiency between different optical channel combinations, remove the limitation on the number of optical channels by the equipment, and improve the scheme design flexibility of the photon correlation experiment.

Description

technical field [0001] The present application relates to the technical field of photon counting, and in particular, to a coincidence counting management method and device. Background technique [0002] With the rapid development of physical optics, people have higher requirements for single photon counting and analysis systems in terms of function and performance. Among them, when people determine the correlation between photons, they need to count the photon generation time data of different optical channels. In order to ensure the normal realization of real-time counting, the common coincidence counting management method in the industry is for each channel combination Correspondingly assign a thread to perform coincidence counting, where the channel combination is a combination of multiple optical channels that need to be coincidently counted. The computing resources occupied by this coincidence calculation management method will increase in a factorial manner when the n...
