摘　　要：使用最小二乘法对LED光谱仪的测试系统进行了研究。结合8组不同波长的LED灯样品进行实验数据,得出了光谱仪的CCD像位和峰值波长之间是高度线性相关的,估计出一元线性回归方程,提出了一种最优波长校准修正方程。实现光谱仪波长快速校准修正,对光谱仪使用具有较强的指导意义。According to the least square method the measurement system of LED spectrometer is researched.Combined with 8 groups of experimental data,we known that the spectrometer phases and peak wavelengths are highly correlated.And the linear regression equation is estimated,an optimal wavelength calibration equation is proposed,realize the rapid calibration and correction of the wavelength of the spectrometer.It has a strong guiding significance for the use of spectrometer.
