A simple all-fiber sensor based on nested fiber balloon rings (FBRs) for simultaneous refractive index (RI) and temperature measurement is proposed and demonstrated. The FBR is easily fabricated by properly bending a section of single-mode fiber. The FBR with a smaller bending radius is embedded...
Generation of these values was based on a dispersion equation which best fits selected data sets covering wide temperature and wavelength ranges. Temperature derivative of refractive index was simply calculated from the first derivative of the equation with respect to temperature. The results are in ...
1. Understanding Refractive Index: The refractive index (n) of a medium is defined as the ratio of the speed of light in vacuum (c) to the speed of light in the medium (v). Mathematically, it is expressed as: n=cv 2. Effect of Temperature on Medium: As the temperature of a me...
The refractive index (index of refraction) is defined as the quotient of the speed of light as it passes through two media, it is a dimensionless number defined as n=c/v. Learn more now!
