Components of a Fiber Optic Sensor
Extrinsic fiber-optic sensors use an, normally a one, to transmit light from either a non-fiber optical sensor, or an electronic sensor connected to an optical transmitter. An example is the measurement of temperature inside by using a fiber to transmit into a radiation located outside the engine. The reflective type, which is a single unit, is available in 3 types: parallel, coaxial, and separate. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of. Due to its small size, low cost and ease of fabrication leading it to replace traditional sensors which were used frequently before th birth of fiber optic sensors.
