A Design and Implementation for Optical Fibre Vibration Sensor

The progress of electronic sensor technology has greatly enhanced the performance of vibration tests, and improved the accuracy and velocity of the measurement. This paper studies and designs a new non-contact optical vibration sensor based on the intensity sensor,and implementation the Optical fibre vibration sensor based on FPGA. The totally available measurement range arrived over 300um. This fiber optic vibration sensor has the advantage of good reliability, low cost, high accuracy measurements.
