摘要
为了减小波长漂移对光谱测量的影响,设计了一个简单的装置,并利用海洋光学公司的HG 1汞 氩光源对PC2000 PC/104光谱仪进行了波长定标。在测量了多条光谱线对应的CCD像元的序数之后,使用回归分析得到波长定标的系数,连同光谱仪出厂时的波长定标系数,计算出了两组定标系数在给定的一些谱线位置处的残差,并利用实验所得的系数对回归方程进行了拟合优度检验,结果表明波长定标模型是有效的。
In order to reduce the effect of wavelength drift on measuring spectrum, a simple device was designed for wavelength calibration of PC2000-PC/104 spectrometer using Ocean Optics' HG-1 Mercury-Argon Lamp. Wavelength calibration coefficients were calculated through regression analysis after several ordinal numbers of CCD's pixels corresponding to Mercury-Argon Lamp's spectral lines were measured. The residuals of certain spectral lines were computed using the coefficients measured and the ones from factory, the degree of fitting for regression equation was estimated using the new coefficients. The final results validated the wavelength calibration model.
