Temperature compensated f iber optic Fabry Perot accelerometer based on the feed

A temperature-compensated fiber optic Fabry-Perot accelerometer (FOFPA) formed by symmetrically bonding an all-silica in-line fiber Fabry-Perot etalon (ILFFPE) and a piezoelectric ceramic unimorph actuator (PCUA) to two surfaces of a silica cantilever is reported. The all-silica ILFFPE with feedback
