A Simultaneous Measurement of Speed and Load of Moving Object Using Fiber Bragg Grating

An optical remote measurement of moving object using fiber grating is demonstrated. The experiment is performed in the laboratory, where the car model is controlled and moved on the moving track, i.e. sensing device unit, the speed and load of the moving vehicle is remotely simultaneous measured. The sensing device is connected to a fiber length of 4 km and signal processing unit for a remote detection and data analysis respectively. The measurement results obtained have shown the possibility of using such a scheme for a remote simultaneous measurement of speed and load of a moving object
