Abstract
Light from a source is communicated to a measurand site. Interferometric means located at the measurand site modulates the light by means of a resonator, the frequency of which is related to the measurand value, said resonator being driven by the modulated light to provide localized oscillator loop closure at the measurand site. Embodiments are disclosed using modified Fabry-Perot and Michelson interferometer designs.
