More Information
Summary:The invention discloses a threshold identification method and circuit based on single photon counting, a terminal and a medium. The method comprises the following steps: counting metering signals to be measured, and determining photon metering numbers respectively corresponding to a plurality of threshold points corresponding to a preset threshold range; constructing a corresponding curve according to the photon metering numbers corresponding to the plurality of threshold points corresponding to the preset threshold range; and smoothing the curve, and analyzing the threshold information of themetering signal according to the smoothed curve. According to the multichannel dose rate monitoring method and device, the corresponding curve is constructed according to the counting result, the threshold information of the metering signal is analyzed according to the curve subjected to smoothing processing, so that the discrimination threshold is adjusted according to the analysis result, and the efficiency and conveni
