Fiber Optical Sensor Application

Fibers have many applications in Remote Sensing. Optical Fiber itself is a sensor in some application. In other cases, Optical Fiber is used to connect a non-fiber optical sensor.

Optical Fiber sensor can be used in measuring Strain, temperature, pressure and so on. Sensors that vary the intensity of the light are the simplest, since it only need a simple source and detector.

Extrinsic Fiber optical sensors use an optical fiber cable, normally a multimode one, to transmit modulated light from either a non-fiber optical sensor, or an electronic sensor connected to an optical transmitter. The major advantage of Extrinsic Sensor is their ability to reach places which others are inaccessible.
