| Abstract: | Optic fiber-grating sensor has many unique advantages and is one of the widely-applied sensors in recent years. The response of FBG sensor to ultrasound was investigated. Results showed that the sensor output intensity was basically linear to the acoustic power. So the optic fiber-grating sensor can be applied to noninvasive detection of internal ultrasound. |
