Experiment Research on an Optical Fiber F-p Ultrasound Sensor for Detecting Internal Defects of Metal Materials
Metal materials have been used in aero industry widely because of its excellent characteristics.So its internal defects are very important.Ultrasound detection technology for detecting metal materials internal defects is related to piezoelectric ultrasonic sensor.This has a few of disadvantages.So the double wavelength optical fiber F-P ultrasound sensing system is designed in this paper.The ultrasound detecting experiment devices for internal defects of metal materials is established based on the optical fiber F-P sensing system.Experimental research of detecting the internal defects is developed.The experimental results show this sensor can detect the ultrasound signals effectively.And its proved that this method can be effective used in the internal defect of metal materials.
