摘　　要：利用连续光谱全反射法,研究了三棱镜的折射率色散特性,增加了测量波长数目.利用最小二乘法进行曲线拟合,给出三棱镜折射率的柯西表达式.The dispersion characteristic of refractive index of triangular prism was researched by continuous total reflection spectrum method, and the number of wavelengths was vastly increased. The Cauchy empirical equation of the refractive index of triangular prism was obtained by least square curve-fitting.
