Exploring the Viability of an All-Fiber Thermal Characterization System
Abstract
In this project, we progress the feasibility of an All-Fiber Frequency Domain Thermoreflectance (FDTR) system through several avenues. 1.) Simulation of the fiber probe in COMSOL coupled with a sensitivity analysis of the system. These sensitivity studies included the probe in a liquid and with the probe contacting a particle. This led to findings for how several parameters such as conductivity of the transducer, thermal boundary conductance with the transducer, and particle size, could affect sensitivity to the surroundings thermal properties. 2.) The Free Space FDTR system was set up and used to characterize transducer alloys. Several experimental techniques, including profilometry, four point probe measurement, and reflectivity measurements were used in tandem with our FDTR system to characterize the potential transducer alloys relative properties, specifically thermoreflectance. 3.) We have constructed the all fiber system ready for validation and have obtained an entirely internal thermoreflectance signal from 4 permutations of novel coated transducers.
