Abstract

The temporal response of fiber optic interferometric thermometers to heat pulses as a function of fiber dimensions is investigated. Theoretical investigations have shown that for applications which require high frequency heat analysis such as turbine engines size of the cladding part of optical fiber is a major limiting factor. To achieve the maximum temporal response a technique is implemented to heat the core of the fiber directly at the cleaved end face. A fiber Fabry-Perot interferometer is formed and its distal cleaved end is black coated. Light from an At⁺ laser is chopped using a Bragg cell and focused at the fiber end to generate high frequency alternating heat source. Time response of 2.5 sec is measured.
