Complex Dynamical Sampling Mechanism for the Random Pulse Circulation Model and Its Application

The fast multi-pulse spectrum is a acquisition method that obtains an average pulse amplitude in dynamic window, which improves the energy resolution by sharpening peaks acquired spectra, but produces counting loss. Owing to loss problem, rate multiplication based on uniform sampling, also called circulation method, presented this paper. Based theory of mathematical statistics and adopted sample pool update real time. Random numbers from distribution were sampled pool, results stored random circulator so information used for generation was uniformly expanded. In experiment section, obtained analyzed verify effect compensation algorithm indicated characteristic each element X-ray spectrogram could realize uniformly, ratio every approximately equal. This great significance obtaining accurate fluorescence spectrum.
