Raman Optical Frequency Domain Reflectometry (ROFDR)

Raman Optical Frequency-Domain Reflectometry (ROFDR) is invented by Farahani and Gogolla in 1998. In the frequency-domain, photons of Raman scattering include Stoke scattering photon and anti-Stokes scattering photon. During the Raman scattering, the photon jumps from the beginning steady-state to another steady-state. According to the Bose-Einstein probability distribution of photons, Stokes Raman scattering power is related to the distribution of temperature.
