Verification of Optical Fiber Multiparameter Sensing Technology for High Temperature Environment

Abstract Aiming at the measurement problems such as strain in high temperature environment, this paper builds an optical fiber sensor that is suitable for high temperature environment. A test system platform that can provide a high temperature environment of 1000 °C both dynamic and static strain loading is designed. The platform includes a high-temperature furnace, constant-strength beams and excitation devices. Based on the test system platform, the thermal strain and loading strain tests of the high temperature fiber optic sensor are completed.
