Fiber Optic Displacement Sensor

The block diagram consists of optical source light emitting diode laser and laser diode optical fiber sensing element optical detector and end processing devices optical spectrum analyzer oscilloscope these sensors are classified into three categories based on the operating principles.

Fiber optic displacement sensor.

Harun 2012 06 22 00 00 00 purpose the purpose of this paper is to propose and demonstrate a simple yet accurate optical fibre based sensor capable of performing micron and sub micron thickness measurement. Principle and major types the optical fiber consists of the core and the cladding which have different refractive indexes. A fiber optic sensor is a sensor that uses optical fiber either as the sensing element intrinsic sensors or as a means of relaying signals from a remote sensor to the electronics that process the signals extrinsic sensors. Fiber optic linear displacement sensor is ideal for real time monitoring of civil engineering structures structural monitoring of aircraft both in flight and on ground smart structures instrumentations concrete structures and other industrial applications where long term reliability is demanded.

Block diagram of fiber optic sensor. Help us write another book on this subject and reach those readers. An orientation dependent displacement and temperature sensor based on the high order coupling mode lp 01 11 of a four mode fiber bragg grating fm fbg is demonstrated. The fotonic sensor is a non contact instrument which uses the fiber optics lever principle to perform displacement measurement vibration analysis and surface condition measurements.

Fiber optic displacement sensors and their applications fiber optic sensors moh. Using the characteristic that the distance apart between the emitting fiber and receiving fiber only shifts the angular power curve a differential reflective fiber optic sensor for angular displacement measurement is presented through subtraction of two power signals from two receiving fibers placed on both sides of one emitting fiber. Fibers have many uses in remote sensing. The fiber optic sensor has an optical fiber connected to a light source to allow for detection in tight spaces or where a small profile is beneficial.

With an appropriate length of fmf the lp 01 11 mode which has a unique mode field generates and a great displacement orientation dependence. Depending on the application fiber may be used because of its small size or because no electrical power is needed at the.
