摘要：

The purpose of this paper is to describe a new method for determination of the total phase difference of light waves without interference fringe counting. One can build up an interferometer for measurement of displacements in which the displacement are determined only by the final values of intensity regardless of the velocity and any prior displacements that caused the present one. The same thing holds true for vibration, relief parameters and other values to be measured. Such an interferometer is devisable thanks to two underlying ideas: first, the application of controllable phase shift, and secondly, the use of properties of integer divisability.
