Abstract

We discuss two methods of obtaining the intensity of light lock fringes formed by two gratings: (1) direct calculation by which the light intensity can be obtained using an analytic formula; (2) the deductive method proposed in this paper. We give several formulas through which the deductive result can be achieved.
