Optical fiber sensor for ultrasonic detection at high temperature

Optical fiber sensor for ultrasonic detection at high temperature

Because of the stable material property of optical fiber up to 1000℃, fiber-optic Bragg grating (FBG) sensor is considered as one of possible ultrasonic sensors used at ultrahigh temperature. However, disappearance of reflectivity of a normal FBG in the high temperature above 900℃ makes the ultrason...
