Abstract
A new approach to detecting relative motion is proposed based on measuring the beat frequency. A formula is derived for the beat frequency as a function of the speed of translation. A principal sketch of an experimental setup implementing the new idea is proposed, and the effects of possible small differences in the frequencies and phases of the sources are discussed.
