What are the different types of Fibre optic sensors?
The optical fiber sensors are divided into two categories: thrubeam and reflective. The thrubeam type comprises a transmitter and a receiver. The reflective type, which is a single unit, is available in 3 types: parallel, coaxial, and separate. The 3 are based on the shape of the crosssection of the optical fiber.
What are the advantages of fibre-optic sensor?
Optical fiber sensors have unique advantages, such as high sensitivity, immunity to electromagnetic interference, small size, light weight, robustness, flexibility, and the ability to provide multiplexed or distributed sensing.
What are different types of fibre optic sensors explain the working of any two sensors?
Fiber optic sensor systems consist of three photoelectric sensing modes such as retroreflective, through-beam and diffuse reflective modes as these systems are operated based on photoelectric sensing technology. Individual and bifurcated sensors are two fiber optic sensing systems that are operated in these modes.
How does a fiber optic sensor work?
Fiber optic sensors work based on the principle that light from a laser or any superluminescent source is transmitted via an optical fiber, experiences changes in its parameters either in the optical fiber or fiber Bragg gratings and reaches a detector which measures these changes.
