Flicker type handheld energy dispersive spectrometer based on sql digitization method and spectrum forming method

Abstract

The invention provides a flicker type handheld energy dispersive spectrometer based on an sql digitization method and a spectrum forming method. The flicker type handheld energy dispersive spectrometer comprises a shell, a power management module, a detector module, a signal processing module, a microcontroller module and an OLED display module, wherein the power management module, the detector module, the signal processing module, the microcontroller module and the OLED display module are arranged in the shell. The power supply management module is used for providing a working voltage for each module of an energy spectrometer system; the detector module comprises a scintillation crystal, a photoconductive device, a photomultiplier and a pre-amplification circuit, and is used for detectingflash generated by ionizing radiation when a substance generates ionizing radiation, converting gamma rays into electric signals and acquiring continuous pulse signals; the signal processing module is used for amplifying and filtering the electric signals output by the detector; the microcontroller module samples an analog pulse signal to realize A / D conversion of data, processes the converted digital signal and transmits the data to the OLED display module; and the OLED display module is used for displaying an operation interface and an energy spectrum diagram.

Description
