Abstract: | Aiming at the problem of traceability of near infrared spectrometer, a metrological verification system was designed. The specifications required being controlled by meterage were analyzed after analyzing the structure and principle of fixed-optics near infrared spectrometer. The verification/calibration/testing methods for all specifications were proposed based on selecting interference filter and neutral density filter and other equipments as standard equipments The peak searching mathematical model was established adopting Gaussian fitting method, and a data analysis system was developed based on LabVIEW program. Experimental results showed that this method will achieve metrological verification of near infrared spectrometer, and solve the problem of its traceability |
