A Simple Fiber Optic displacement Sensor for Measurement of Light Intensity with the Displacement
نویسنده
چکیده
Abstract Over the last two decades, the fibre optic technology has passed through many analytical stages. Some commercially available fibre optic sensors are being used for automation in mechanical and industrial environments. They are also used for instrumentation and controls. In the present work, a fibre optic displacement sensor is presented. This type of sensor is an intrinsic sensor. In this paper our aim is to study the different results of displacement sensor using fibre optic coupler.

Fiber - Optic Sensing of Linear Thermal Expansion (RESEARCH NOTES)
The use of a LED fiber-optic sensor to measure displacement and linear thermal expansion is described. It has a sensitivity of about 0.6 mV/mm, a resolution of 1.25 mm, and a dynamic rang of 400 mm for displacement measurements. For thermal expansion, it shows a sensitivity of about 3.5 mV/C, and the experimental linear expansion values are in agreement with those calculated. The reported senso...

متن کاملAn Intensity-Modulated Optical Fibre Displacement Sensor with Convex Reflector
A novel intensity-modulated optical fibre displacement sensor with convex reflector technology is described. A common form of the intensity-modulated optical fibre sensor performs its measurement by making use of a pair of straight optical fibres with a plane reflector. The reflected optical signal intensity changes as a function of change in displacement. This paper describes an alternative se...
متن کاملDevelopment of an Optical Fiber Sensor for the Measurement of Angular Displacements in Anthropomorphic Systems
Due to the arising importance and widespread role of robotic systems, it is fundamental the development of high-performance position sensors. There are several existing methods to determine position of anthropomorphic manipulators. However, they present limitations, such as vulnerability to electromagnetic fields or application of mechanical load to the system. Concerning these problems, an opt...
