Abstract

The near infrared spectroscopy (NIRS) is the main apparatus for near-infrared spectrum analysis, which has been widely used in agriculture, biology, petrifaction, foodstuff, medicament, spinning and other fields. In this paper, we successfully designed a high-sensitivity, high-resolution, high-speed, real-time and USB2.0-based near infrared spectroscopy data acquisition system, and discussed the design ideas of multi-functional NIR spectrometer on hardware and software. On the basis of deeply analysis of the construction and principle of near infrared spectrometer and principle of optics, we set up the near infrared spectroscopy system, developed the software system of data acquisition and data processing, did some preliminary experiments and made analysis on the results. The results of the experiments demonstrate the instrument can reflect the spectral characteristics of YAG laser and meets the design requirements.
