Wavelength calibration for miniature fiber optical spectrometers
摘要
Abstract
In order to improve the measurement accuracy of the miniature fiber spectrometer, a complete calibration scheme was obtained based on the standard emission spectrum of mercury and argon lamp and three-order linear fitting of the least squares. Calibration results show that the arithmetic mean error is less than 0. 167nm, standard deviation is less than 0. 217nm and the fitting related degree is high. Test results show that after calibration the wavelength uncertainty is better than the 0. 11nm, the error is less than 0. 15nm, and the wavelength repeatability can reach 0.01nm. This result is beneficial for improving the measurement precision of spectrometers in the practical applications.关键词
