Abstract

The invention discloses a relaxation spectrum detection device and method. The relaxation spectrum detection device comprises a computer, a visible / near-infrared spectrometer, a sample pallet arranged in a lightproof sample cell, a halogen lamp, and a light source controller and a fiber-optic probe both electrically connected with the halogen lamp, wherein the sample cell is provided with a collecting end; the fiber-optic probe is separately connected with the visible / near-infrared spectrometer and the halogen lamp via a bifurcated optical fiber; and the computer is in data connection with the visible / near-infrared spectrometer. The relaxation spectrum detection device provided by the invention has the characteristics of high detection efficiency and high detection precision.

Description

technical field [0001] The invention relates to the technical field of spectrum detection, in particular to a relaxation spectrum detection device and method 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 saturati...
