Research Abstract	The new optical FIber Bragg Grating (FBG) distortion sensor was suggested. This system consists of FBG and a narrowband LD light source and photodetectors. The proposed technique can make a compact and high-speed measurement system and it is possible to construct it at a lower price. This system makes amends for the error of measurement by the temperature with installing FBG for the temperature compensating.
