09 Apr 1987TL;DR: An optical physical condition sensor includes an optical fiber resonant cavity into which optical energy, including wavelengths resonatable within the cavity, is introduced as mentioned in this paper, and external physical conditions such as temperature or pressure, change the effective optical path length within a cavity to cause a corresponding change in the cavity's resonant characteristics.
Abstract: An optical physical condition sensor includes an optical fiber resonant cavity into which optical energy, including wavelengths resonatable within the cavity, is introduced. External physical conditions, such as temperature or pressure, change the effective optical path length within the cavity to cause a corresponding change in the cavity's resonant characteristics. Changes in the sensed condition can be determined as a function of changes in the wavelength of optical energy peaks or minimas in the cavity or changes in the cavity's finesse characteristics.
