A Multi-Groove Ceramic-Packaged Sapphire-Diaphragm Fiber Sensor for High-Temperature Vibration

A sapphire-diaphragm fiber-optic vibration sensor for high-temperature applications is proposed and experimentally demonstrated. Its sensing unit consists solely of a monolithic sapphire sensitive diaphragm encapsulated in a multi-groove ceramic housing, forming a stable Fabry-Pérot interfero...
