On the ultimate sensitivity in coordinate measurements

Abstract

An analysis of the sensitivity of coordinate meters for ultimate precision mechanical experiments is presented. It is shown that the existing sensitivity of coordinate meters ΔLf≅10-16-10-18cm √Hz can be substantially improved and reach ΔLf≅10-21-10-23cm √Hz using new types of microwave and optical parametric transducers based on high-Q dieletric resonators. © 1993.
