分光计测棱镜玻璃折射率实验的色散谱线因折射定律而成为曲线.长期以来,由于数学分析与计算的难度,解出该曲线的数学表达式——谱线形状函数成为数学上的一个难题.通过深入分析三棱镜对单色光折射的光路结构,确定了出射光的方位角,由此解出正交条件下谱线的形状函数,再通过坐标转换,导出一般情况下谱线的形状函数,解决了这一难题.谱线形状函数的图像与对应的实际谱线比较,两者一致.
Shape function of spectral line in experiment of measuring refractive index of prism glass with spectrometer
The dispersion spectral line of the experiment of measuring refractive index of prism glass with spectrometer becomes a curve due to the law of refraction.Because of the difficulty of mathematical analysis and calculation,figuring out the mathematical expression of this curve,the shape function of spectral line,has become a long-standing difficult problem in mathematics.The azimuth of emergent ray was calculated by analysing in depth the light path structure of monochromatic light refracted by prism.From this,the shape function of spectral line in orthogonal condition was figured out.And then,by coordinate transformation,the shape function of spectral line in general case was derived,thus solving the difficult problem.Compared the image of the shape function to the corresponding actual spectral line,they are consistent.
