A theoretical analysis of the fringe pattern produced by a capillary tube interferometer is presented, which is expected to be two-beam interference, and a computer program to simulate the interference fringe pattern is established. By comparing the simulated fringe pattern and the experimental fringe pattern, the refractive index of the liquid can be given when the two fringes coincide best. The results of this method are close to those of the Abbe refractometer.
对毛细管干涉仪产生的条纹图案进行了理论分析，预计其为双光束干涉，并建立了一个模拟干涉条纹图案的计算机程序。通过比较模拟条纹图案和实验条纹图案，当两者条纹最佳重合时可得出液体的折射率。该方法的结果与阿贝折射仪的结果相近。
