Fiber optic angular displacement sensor

A reflective type fiber optic angular displacement sensor has recently been developed, which consists of a light source, an optical isolator, a four-port single-mode fiber bidirectional coupler, and a light intensity detection system (two silicon photodetectors and ananalog divider). By using a normal He-Ne laser with &2% stability in light intensity, we have achieved an angle resolution of 10e...

A Simple Fiber Optic displacement Sensor for Measurement of Light Intensity with the Displacement

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 t...

A Fiber Optic Sensor for the Measurement of Surface Roughness and Displacement Using Artificial Neural Networks

This paper presents a fiber optic sensor system. Artificial neural networks (fast back-propagation) are employed for the data processing. The use of the neural networks makes it possible for the sensor to be used both for surface roughness and displacement measurement at the same time. The results indicate 100% correct surface classification for ten different surfaces (different materials, diff...

Fiber Optic Displacement Sensors and Their Applications

Optical fiber-based sensor technology offers the possibility of developing a variety of physical sensors for a wide range of physical parameters (Nalwa, 2004). Compared to conventional transducers, optical fiber sensors show very high performances in their response to many physical parameters such as displacement, pressure, temperature and electric field. Recently, high precision fiber displace...

Measurement of Displacement of Optical Fiber Using Light Intersection Method

Connecting method of optical fibers by V-shaped groove is used in various fields. And in this met,hod, i t is important to estimate distortion of a fiber, because a distortion of the optical fiber influences a connection characteristics. We developed measurement technique of a n optical fiber distortion using Light Intersection Method and optimized incidence angle of the laser beam on a Sample ...
