Fiber optic sensing: Input and Output

Fiber optic sensing Input: Light beam that carries the information

Output:

Extrinsic: 1. encoder plates/disks: linear and angular position 2. Evanescence: temperature, strain 3. reflection and transmission: pressure, flow, damage 4. Laser Doppler velocimetry: flow measurement 5. total internal reflection: liquid level, pressure 6. absorption Band edge: temperature 7. Gratings: Pressure, Acoustics, vibrations 8. Photo elastics effects: pressure, acceleration, vibration, rotatory, position.9. Fluorescence: temperature, viscosity, chemical analysis. 10. Pyrometers: temperature.

Intrinsic: 1. Microbends sensors: strain, pressure, vibration. 2. blackbody sensors: temperature 3. interferometryc sensors: rotation acceleration, acoustics, magnetic fileds, electric fields, strain, temperature, pressure, current.
