An Optical Fiber Displacement Sensor Using RF Interrogation Technique
We propose a novel non-contact optical fiber displacement sensor. It uses a radio frequency (RF) interrogation technique which is based on bidirectional modulation of a Mach-Zehnder electro-optical modulator (MZ-EOM). The displacement is measured from the free spectral range (FSR) which is determined by the dip frequencies of the modulated MZ-EOM transfer function. In experiments, the proposed ...
متن کاملPlastic Optical Fiber Displacement Sensor Based on Dual Cycling Bending
In this study, a high sensitivity and easy fabricated plastic optical fiber (POF) displacement sensor is proposed. A POF specimen subjected to dual cyclic bending is used to improve the sensitivity of the POF displacement sensor. The effects of interval between rollers, relative displacement and number of rollers on the sensitivity of the displacement sensor are analyzed both experimentally and...
متن کاملA Differential Reflective Intensity Optical Fiber Angular Displacement Sensor
In this paper, a novel differential reflective intensity optical fiber angular displacement sensor was proposed. This sensor can directly measure the angular and axial linear displacement of a flat surface. The structure of the sensor probe is simple and its basic principle was first analyzed according to the intensity modulation mechanisms. Secondly, in order to trim the dark output voltage to...
متن کاملFiber 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...
