dc.description.abstract This paper describes the design of an intensity based fiber optic displacement sensor, which can measure the amplitude and frequency of the vibration . The proposed device consists of a fiber optic transmitter, photodiode detector, fiber optic proves, digital oscilloscope , POF fiber, an elastic cantilever & power source. Light from the fiber optic transmitter is coupled into the transmitting fiber. Then the signal will be reflected from the cantilever, coupled to the receiving fiber and is detected by the photo detector . Then the signal is converted to voltage and is measured by the digital oscilloscope . This sensor should be capable of measuring vibration having amplitude ranging from 0.008 to 0.74mm and frequency ranging from 75 to 275 Hz. This fiber optic vibration sensor can be used vastly in high power electric plants and also to detect earthquakes, different problems in aircraft and in robotics. en_US
