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

The present application provides a method and device for managing coincidence counts. The method includes: receiving a coincidence counting instruction instruction, and analyzing the coincidence counting instruction instruction, to obtain a plurality of counting combinations and channel data of each counting combination; and judging whether there is an existence between each counting combination according to the obtained channel data of each counting combination Combining inclusion relationships, and dividing multiple counting combinations with combined inclusion relationships into the same counting strategy; obtaining the photon generation time data of each optical channel corresponding to each counting strategy, and recording them within the time period corresponding to the preset counting duration , controlling the thread corresponding to the counting strategy to perform coincidence counting on each optical channel corresponding to the counting strategy based on the preset time window width and the corresponding photon generation time data. The method can save the computing resources of the system, improve the coincidence counting efficiency between different optical channel combinations, relieve 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 method and device for coincidence counting management. 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, it is necessary to count the photon generation time data of different optical channels. To ensure the normal realization of real-time counting, the current common management method of coincidence counting in the industry is for each channel combination. Correspondingly, a thread is allocated to perform coincidence counting, wherein the channel combination is a combination of multiple optical channels that need to be coincidently counted. When the number of channels changes linearly, the computing resources occupied by this method of computing ...
