Brief
This Master's thesis researches the sensing characteristics of fused biconical taper optical microfiber couplers with a hybrid structure, focusing on their application in axial micro strain and salt solution concentration sensing, and demonstrates the hybrid structure's potential for combining high-precision and large-range strain measurement.
Summary
This Master's thesis investigates fused biconical taper optical microfiber couplers with a hybrid structure for axial micro strain and salt solution concentration sensing. The thesis also examines the sensing properties of a standard 2x2 fiber coupler for temperature, axial micro strain, and salt concentration. The proposed hybrid structure, combining a microfiber coupler and a Mach-Zehnder interferometer, aims to achieve both high precision and a large measurement range for axial micro strain. The research includes the fabrication and experimental validation of these fiber optic sensors.
