The 1930 Nobel Prize in Physics was awarded to Sir Chandrasekhara Venkata Raman "for his work on the scattering of light and for the discovery of the effect named after him."

The High-Resolution Raman Sensing Teaching & Research System developed by Jiuzhang Quantum is based on the principles of Optical Time Domain Reflectometry (OTDR) and Raman scattering. Using the transmission optical fiber itself as the sensing element, the system analyzes the characteristics of backscattered Raman light generated by the interaction between injected laser pulses and the optical fiber, enabling the inversion of spatial temperature distribution changes along the fiber length. Powered by a picosecond pulse laser source, this system not only visually demonstrates the Raman scattering phenomenon in optical fibers, but also achieves distributed optical fiber sensing with centimeter-scale spatial resolution, helping students explore the engineering applications of optical fiber sensing based on a solid understanding of scientific principles.
