Abstract

An electromagnetic immune fiber-optic microvibrated sensor systems with cantilever-type sensing element are perspective for investigation of ground traffic monitoring, for earthquake forecasts, motor diagnostics, etc. An acceleration sensitivity of vibrated fiber tip will be analyzed and compared with another traditional approaches. The most of low-frequency accelerometers have been based on the seismic mass effect. But this different way of detecting of the movement of the seismic mass is by allowing it to produce of the micro stresses in the fiber body, which are detected by grating's spectrum immediately. This type sensor system was developed and realized in certain experiments to measure of the ground vibration excited by acoustic emission and mechanical interaction between the motor and the ground. But the whole potentials of high sensitivity of fiber-optic sensors with inner fiber gratings were not realized enough yet in experiments. (Abstract only available)
