Theory of a three-beam interferometer
This paper describes a new theory and the related analysis method of "interference", which are quite different from the traditional Zernike three-beam interferometer. Formulas are given for calculating the optical transfer function of a three-beam system. Values of the optical transfer function and the accuracy of the system are also calculated.
