AI Technical Summary

Problems solved by technology

[0004] Due to the limited detection range of the detector and the 4π solid angle distribution of the signal generated by positron annihilation, the efficiency of collecting the time signals measured by the two detectors is low. At the same time, the existing signal processing device can only output one output signal for one input signal. Different input signals The output signals are independent of each other. When processing multiple signals with time correlation, the existing signal processing device cannot complete independently.

Abstract

The disclosure relates to a signal processing device and a time detection device. The signal processing device is used for receiving multi-path input signals; and when any path of input signal meets a preset condition; and a logic level is triggered, all logic levels are outputted and combined to form an output signal. Therefore, the signal processing efficiency can be doubled.

Description

technical field [0001] The present disclosure relates to the technical field of signal processing, and in particular, to a signal processing device and a time detection device. Background technique [0002] In nuclear spectroscopy, signal processing technology is widely used, for example, it can be applied to positron emission computed tomography (PET, Positron Emission Computed Tomography), positron annihilation lifetime spectroscopy (PALS, Positron Annihilation Lifetime Spectrum) ) measurement and positronium time-of-flight spectrum (Ps-TOF, Positronium Tpectrum-Time Of Flight) measurement medium. [0003] The above signal processing process is to use a detector to detect the start signal of one input signal, and the signal from the detector enters a timer to generate a start time signal after being pre-amplified; another detector is used to detect the end signal of the input signal , the signal from the detector enters another timer to generate a termination time signal ...
