Paper Abstract

Fiber Bragg grating (FBG) sensors have been used to monitor the axial and radial strain induced in a 30 mm caliber gun barrel by the passage of a projectile with a muzzle velocity of greater than 1 km/s. The performance of the sensors is compared with that of conventional resistive foil strain gauges. The FBG sensors were used to monitor transient strain signatures of duration less than 100 microseconds with rise times less than 10 microseconds and magnitude 10,000 micrometers/m.
