Abstract:
1. A method for digitalizing scintillation pulses, comprising: step (1) comprising: defining n threshold voltages V_th according to a characteristic of the scintillation pulses, wherein n is an integer greater than 1 and less than 512; step (2) comprising: forming a voltage comparison unit by n low-voltage differential signaling receiving ports, outputting, by the voltage comparison unit, a state-flip and a threshold voltage corresponding to the state-flip when the scintillation pulse to be sampled exceeds any one of the thresholds set in step (1); wherein the low-voltage differential signaling receiving ports are configured to compare the scintillation pulses with the threshold voltages; step (3) comprising: sampling digitally a time when the state-flip in step (2) occurs by a time-to-digit converter and identifying the threshold voltage corresponding to the state-flip, to acquire the voltage and the time for the scintillation pulse to implement digitalization of the scintillation pulses.
