Light Sensing Capacity of Fiber Optic Sensor
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 intrinsi.

The principle of fiber optic communication is refraction
The principle of fiber optic operation is based on Snell's law, which describes the phenomenon of light refraction when passing through the boundary between two mediums with different refractive indices. It is represented as − $$n = frac {c} {v}$$ Where, c = the speed of light in free space = 3 × 10 8m/s v = the speed of light in di-electric or non-conducting material. Refraction and total internal reflection (TIR) are the two fundamental optical principles that allow light to propagate through optical fibers over long distances with minimal loss. Refraction refers to the bending of light as it passes from one substance to another. As the glass used in the fiber core has a higher refractive.

Here we propose a high-resolution fiber ring magnetometer based on laser frequency stabilization technology. By connecting one output port to an input port of a fiber coupler with a splitting ratio of 1:99, the fiber ring resonator (FRR) generates a series of highly narrow transmission resonances.
