Home / Working principle of fiber optic voltage sensor
Optical fibers can be used as sensors to measure, , and other quantities by modifying a fiber so that the quantity to be measured modulates the, ,or transit time of light in the fiber. Sensors that vary the intensity of light are the simplest, since only a simple source and detector are required. A fiber optic sensor works on the principle of light from a superluminescent source or a laser transmitted through an optical fiber then it experiences changes within its parameters either in the fiber Bragg gratings or optical fiber & reaches a detector that measures these. Fiber optic sensors play a key role in developing the communication system to sense & measure the change within phase, data transmission rate, wavelength, intensity, noise, uneven environmental conditions, extreme heat, high vibration, etc. 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. Further there are many points why fiber optic sensors are used in place of traditional size and.

Key learnings: LDR Definition: A light-dependent resistor is defined as a device whose resistance decreases with increasing light intensity and increases with decreasing light intensity.
Optical fibers can be used as sensors to measure strain, temperature, pressure and other quantities by modifying a fiber so that the quantity to be measured modulates the intensity, phase, polarization, wavelength or transit time of light in the fiber. Sensors that vary the intensity of light are the simplest, since only a simple source and detector are required. A particularly useful feature of intrinsic fiber-optic sensors is that they can, if required, provide distributed sensing over very large distances.
