METHOD AND DEVICE FOR EXTRACTING SCINTILLATION PULSE INFORMATION

摘要

A method for extracting scintillation pulse information includes followed steps: 1. obtaining a peak value of the scintillation pulse in a certain energy spectrum, and setting at least three threshold voltages according to the peak value; 2. determining the time when the scintillation pulse passes through the each threshold voltage, wherein each time value and its corresponding threshold voltage form a sampling point; 3. selecting multiple sampling points as sampling points for reconstructing and reconstructing pulse waveform; 4. obtaining the data of original scintillation pulse by using reconstructed pulse waveform. A device for extracting scintillation pulse information includes a threshold voltage setting module (100), a time sampling module (200), a pulse reconstruction module (300) and an information acquiring module (400).
