Description

technical field [0001] The invention relates to the technical field of spectrum detection, in particular to a method of a relaxation spectrum detection device with high detection efficiency and high detection precision. Background technique [0002] Status: Visible / near-infrared spectral analysis technology has the advantages of simplicity, non-destructiveness, rapidity, suitable for analysis objects in various states, and suitable for online detection. It has broad application prospects in the food industry. [0003] The main defects of the existing equipment are: (1) The current spectral detection technology adopts static spectral technology, which only focuses on the reflection or projection light parameter characteristics after the light beam is irradiated on the detection sample and reaches stability. (2) The characteristic functional groups of the internal chemical components of the food sample quality have different absorption effects on the spectrum under the saturat...
