本文利用菲涅耳方程式[2],在入射角θ_1=45°情况下,直接导出一种新的测量折射率的公式,与Collett用斯托克斯参量和Mueller矩阵推导的结果完全相同[1]。分析了用此公式进行测量可达到的精度。
In this paper, we use Fresnel equation [2] to directly derive a new formula for measuring the refractive index at θ_1 = 45 ° angle, which is exactly the same as Collett’s derivation with Stokes parameters and Mueller matrix [1 ]. The accuracy achievable with this formula is analyzed.
