【Abstract】 A new grating optical fibre sensor for measuring the displacement and vibration with conventional grating measurement and modern optical fibre technology combined is developed. The factors affecting the accuracy of the sensor and experiments for monitoring the vibration performed with the new fibre and complete micro-computer measuring system are discussed. The advantages of the new sensor, such as immunity to electromagnetic interference and intrinsic safety in hazardous environment make it particularly suitable for use in detecting vibration, displacement, or pressure in power plants, oil fields, and coal mines.更多还原
