Fiber Optics: Understanding the Basics
• Sensing — Fiber optics can be used to deliver light from a remote source to a detector to obtain pressure, temperature, or spectral information. The fiber itself

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 insideby using a fiber to transmit into a radiation located outside the engine. The transducer modulates a parameter of the optical fiber system, such as intensity, wavelength, polarization, or phase. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. 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.
