Fiberoptic sensing of temperature and/or other physical parameters

Abstract From the Canadian patent

Several specific types of optical sensors capable of measuring temperature, pressure force, accel-, leration, radiation and electrical fields fluid level, vapor pressure, and the like are disclosed, along with an, electro-optical system for detecting the optical signal developed by the sensor. One such probe utilizes a convex shaped structure consisting of an elastomeric material attached to an end of an optical fiber the, elastomeric material being coated with a luminescent material, a combination that is capable of measuring both temperature and pressure. Such a probe is also specifically adapted for measuring surface temperature by making a good physical contact with the surface being …
