摘要
使用在迈克耳孙干涉仪的反射镜前插入附加玻璃板的方法实现了白光的等倾干涉,观察到干涉条纹在出现范围、衬比度、颜色等方面的基本特征;通过建立以色散为基础的理论模型,得到了条纹衬比度函数的简洁数值计算方法和近似解析表达式,并对这种白光等倾干涉的条纹特征和形成机理进行了全面解释.
The white-light equal-inclination interference is implemented by inserting a glass plate before a mirror of the Michelson interferometer, and features in appearing range, contrast and color of the interference fringes are observed. Based on dispersion, a concise digital computation expression and an approximate analytical expression are established to determine the contrast of the fringes, and the fringe features are completely explained.
