Centroid Algorithm for Scalable Fluorescence Lifetime Detection

The present invention belongs to the field of electrical engineering, and the technical scheme adopted in the invention is to expand the fluorescence lifetime, and to extend the detectable fluorescence lifetime range so that the detectable fluorescence lifetime range is not affected by the frequency of the induced fluorescence laser pulse and the quantization range of TDC. The centroid algorithm CMM of the detection range comprises the following steps: f (t) = Aexp (-t/T) For a single exponential response (1). CMM algorithm accuracy and error of the relationship as shown in the description.The standard deviation of the corrected fluorescence lifetime is shown in the description. The present invention is mainly applied to the detection of fluorescence lifetime.
