Investigation of High Temperature Silica Based Fiber Optic Sensor Materials

To meet performance metrics of energy conversion systems such as advanced boiler systems, combustion turbines and solid oxide fuel cells, operators are looking towards advanced sensor and monitoring systems to improve their reliability, efficiency, safety and security. The high temperature and harsh environments that are required to operate these systems often necessitate the use of fiber optic sensors over more traditional sensing technologies. To this end, there is a need for fiber optic sensing system integration at a realistic cost point and an alternative to sapphire fiber optics, which are more expensive and require additional expertise
