Abstract

The present invention discloses a multi-channel portable spectrum system based on time-sharing lightening and a detection method thereof. The system replaces grating with a linear filter to greatly save the space required by dispersion and unfolding of input light by the grating, compared to a grating spectrometer, the portability of the spectrum system is improved; a time-sharing lightening technology is employed to allow a plurality of light sources to still flicker in a sample groove so that measurement is completed in seconds, compared to the grating spectrometer, the measurement speed ofthe spectrum system and the number of the detection samples measured each time are increased to greatly improve the work efficiency of the spectrum system; the spectrum system employs an n-in-one optical fiber beam splitter to allow the information light of the detection samples in the channels to be all transmitted to one linear CCD element, and compared to the grating spectrometer, the experiment operation is simplified to further save the space and improve the portability; and moreover, the manufacturing cost and the manufacturing difficulty are greatly reduced.

Description

technical field

[0001] The invention relates to spectrum detection technology, in particular to a multi-channel portable spectrum system based on time-sharing lighting and a detection method thereof. Background technique

[0002] When light acts on matter, various spectral phenomena such as light transmission, scattering, absorption and emission spectra will be produced. According to the spectral characteristics, relevant information such as the composition and content of the substance under study can be obtained. Therefore, spectral detection technology is widely used in many fields such as biochemical detection, biomedicine, environmental monitoring, health and quarantine, food and pharmaceuticals, industrial and agricultural production, and astronomical observation. A spectrometer is one of the means to achieve spectral detection. It is a scientific instrument that uses photodetectors such as photomultiplier tubes to obtain the intensity of spectral lines at different wav...
