Abstract

The invention discloses a spectrum acquisition system and a spectrum acquisition method for a scintillation light source. The system comprises a scintillation light source, a spectrometer and a controller, wherein the output end of the controller is electrically connected with the input end of the scintillation light source; the input end and the output end of the controller are connected with the input end and the output end of the spectrometer; the controller is used for controlling the scintillation light source and the spectrometer to be synchronous according to the set input scintillation light source triggering times, the spectrometer integral time and the spectrum average times, light source spectrum and dark spectrum data information gathered by the spectrometer is acquired effectively in real time, the average light source spectrum data and the average dark spectrum data are acquired according to the spectrum average times, and finally, the average dark spectrum data are subtracted from the gathered average light source spectrum data to obtain the spectrum data for the scintillation light source at each time. Thus, the scintillation light source and the spectrometer data work cooperatively, and the spectrum data precision is improved.

Description

technical field

[0001] The invention relates to the field of optical detection, in particular to a spectrum acquisition system and a spectrum acquisition method of a flashing light source. Background technique

[0002] Light is emitted by a light source. At present, the light source for spectral analysis is mainly used. The most important components in spectral analysis are the spectrometer and the light source. The spectrometer is an important optical measuring instrument, through the analysis of the characteristic spectral lines, the qualitative and quantitative analysis of the composition of the substance is carried out. Another important device for spectral analysis is the light source. The stable performance of the light source is the basic requirement for spectral analysis. There are many kinds of light sources for the spectrum, such as xenon lamp, deuterium lamp, mercury lamp and so on. Therefore, the light source can be divided into continuous light source and flas...
