Optical fiber sensing technology is gradually formed with the development of optical communication technology.
Compared with traditional sensors, fiber optic sensors have a series of unique advantages, such as high sensitivity, anti-electromagnetic interference, corrosion resistance, good electrical insulation, explosion-proof, flexible optical path, easy to connect with computers, simple structure, volume Small, light weight, low power consumption, etc.
Optical fiber sensors can be divided into functional and non-functional types according to the sensing principle.
The functional fiber optic sensor uses the fiber itself as a sensitive element, so it is also called a sensing fiber optic sensor, or an all-fiber sensor.
Non-functional fiber optic sensors use other sensitive elements to sense the changes to be measured. The fiber is only used as a transmission medium to transmit optical signals from distant or inaccessible places. Therefore, it is also called a light-transmitting sensor. or hybrid sensors. Optical fiber sensors can be divided into:
Intensity Modulated Fiber Optic Sensors
Phase Modulated Fiber Optic Sensors
Frequency Modulated Fiber Optic Sensors
Polarization Modulated Fiber Optic Sensors
Wavelength (color) modulated fiber optic sensor
