Error correction of spectral response characteristic of grating spectrometer
摘要
Abstract
Aiming at the big measuring error from grating spectrometer caused by the devices′spectral charac-terics, an error correction method is brought forward and validated .Firstly, the grating spectrometer′s princi-ple is analyzed deeply and the theoretical model of error correction is built .Then, the spectral characteristics of key devices, such as grating, detector, mirror etc., are studied and the algorithm of numerical extraction is brought forward to acquire the value of each point on the spectral curve .Finally, the theoretical model and the method of numerical algorithm are used to correct the bromine-tungsten lamp′s spectrum which is obtained by the grating spectrometer .The result of the experiment shows that the mean error of the numerical extraction al-gorithm is only 0.39%, and the corrected spectrum is very close to the standard spectrum , which certifies that the correction method brought forward in this paper can eliminate the errors brought by the devices ′spectral characteristics.关键词
