A Framework for Spontaneous Brillouin Noise: Unveiling Fundamental Limits in Brillouin Metrology
Simeng Jin, Shuai Yao, Zhisheng Yang +7
Spontaneous Brillouin scattering (SpBS) provides a non-contact tool for probing the mechanical and thermodynamic properties of materials, enabling important applications such as di…
