Abstract

The invention discloses a full-band near-infrared sensor, which comprises a switching power supply circuit, an ADC sampling circuit, a DAC output amplification circuit, a microprocessor and a near-infrared sensor group, the microprocessor is electrically connected with the near-infrared sensor group through the DAC output amplification circuit and the ADC sampling circuit; the near-infrared sensor group comprises a plurality of near-infrared sensors; the switching power supply circuit determines different detection wavebands by applying the same power supply voltage to different near-infrared sensors. Different near-infrared light detection ranges can be obtained by applying the voltage within the same range to the different sensors in the near-infrared sensor group, and the flexible and wide near-infrared light detection range can be obtained on the premise that the influence on the equipment size is small by freely selecting the sensors in the near-infrared sensor group.

Description

technical field [0001] The invention relates to the field of near-infrared spectrum detection, in particular to a full-band near-infrared sensor. Background technique [0002] The near-infrared spectrum is an electromagnetic radiation wave between visible light (Vis) and mid-infrared (MIR). The American Society for Testing and Materials (ASTM) defines the near-infrared spectrum as the region of 780-2526nm, which is found in the absorption spectrum. The first non-visible light zone. The near-infrared spectrum region is consistent with the combined frequency of the vibration of hydrogen-containing groups (O-H, N-H, C-H) in organic molecules and the absorption region of all levels of frequency multiplication. By scanning the near-infrared spectrum of the sample, the hydrogen-containing groups of organic molecules in the sample can be obtained. The characteristic information of the cluster, and the use of near-infrared spectroscopy to analyze samples has the advantages of conve...
