Fibre Optic Sensor for Speed Measurement

Fibre optic sensor for speed measurement This thesis is dedicated to my son David and m y wife Paula Fibre optic sensor for speed measurement page 2 Determination of speed is an important requirement in a wide variety of technical and industrial applications. The measurement of speed has evolved from pure mechanical to magnetoelectric and radio frequency (RF) based devices. There is however a demand for low-cost sensors capable of operating in potentially hazardous environments in which optical fibre sensors are more suited. In this thesis the development of a non-intrusive speed measurement sensor, based on optical technology is described. The optical fibre sensor described herein gives an almost instantaneous indication of the speed and is compared to a commercial speed senso
