Fiber optic displacement sensor.

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. 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. Depending on the application fiber may be used because of its small size or because no electrical power is needed at the. 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.

Harun and hamzah arof intechopen doi. Over 21 000 intechopen readers like this topic. Principle and major types the optical fiber consists of the core and the cladding which have different refractive indexes. 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.

Help us write another book on this subject and reach those readers. Our engineers can help you design that special sensor to meet your unique application requirements. 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. Fibers have many uses in remote sensing.

With an appropriate length of fmf the lp 01 11 mode which has a unique mode field generates and a great displacement orientation dependence. 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. Philtec provides innovative fiber optic displacement sensing solutions to customers around the world. 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.

The fotonic sensor transmits a beam of light through a flexible fiber optic probe receives light reflected from a target surface and converts this light into an electrical signal proportional to the distance.
