Abstract

A novel interferometric technique is described which exploits the relationship between an optical resonator's length and resonant frequency. This concept has potential for measuring length variations of an order of « l Λ. This paper briefly describes the concept, the experiment performed to demonstrate the concept, and the experimental, results. Results obtained indicate a repeatability in the measured data to ∼/5 Λ rms.
