A Self-Referencing Intensity Based Polymer Optical Fiber Sensor for Liquid Detection
A novel self-referencing fiber optic intensity sensor based on bending losses of a partially polished polymer optical fiber (POF) coupler is presented. The coupling ratio (K) depends on the external liquid in which the sensor is immersed. It is possible to distinguish between different liquids and to detect their presence. Experimental results for the most usual liquids found in industry, like ...
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 کاملDetection of Fuel Adulteration in Real Time Using Optical Fiber Sensor and Peripheral Interface Controller
Detection of fuel adulteration in real time is the most important need of the world as it generates the hazardous effects on the environment, living and nonliving things. Various automotive users and fuel providers may mix kerosene in petrol and diesel. Adulterated fuel increases air pollution, as well as reduces the performance of vehicle engines. Such a malpractice in fuel is prevailing becau...
متن کاملTriangularly phase-modulated optical fiber ring resonator sensor.
An optical fiber ring resonatory sensor system has been demonstrated by applying a triangular phase modulation signal to a fiber loop. The dynamic range for detection of optical phase change is 2pi. The sensor is linear within this range. The minimum detectable optical phase change is 1.5 x10(-4) rad/Hz((1/2)).
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...
