双光束干涉仪的波前误差
Wavefront errors in a two-beam interferometer
摘要：
本文讨论了由双光束干涉仪的光学像差引起的波前误差对积分干涉条纹所观察到的行波条纹周期的影响。干涉仪操作的蒙特卡罗模拟表明，如果基于进入干涉仪的光束的角谱来评估，则条纹周期估计是无偏的，但是波前误差增加了不确定性。
英文摘要：
The paper deals with the impact of wavefront errors, due to the optical aberrations of a two-beam interferometer, on the period of the travelling fringe observed by integrating the interference pattern. A Monte Carlo simulation of the interferometer operation showed that the fringe-period estimate is unbiased if evaluated on the basis of the angular spectrum of the beam entering the interferometer, but the wavefront errors increase the uncertainty.
