Brillouin spectrometer
Webdispersive (grating) spectrometer. Applications Brillouin spectroscopy is the most frequently used technique for measurements of single-crystal elastic properties of … Brillouin spectroscopy is an empirical spectroscopy technique which allows the determination of elastic moduli of materials. The technique uses inelastic scattering of light when it encounters acoustic phonons in a crystal, a process known as Brillouin scattering, to determine phonon energies and … See more Brillouin spectroscopy is similar to Raman spectroscopy in many ways; in fact the physical scattering processes involved are identical. However, the type of information gained is significantly different. The process observed … See more Brillouin spectroscopy is a valuable tool for determining the complete elastic tensor, $${\displaystyle c_{ijkl}}$$, of solids. The elastic tensor is an 81 component 3x3x3x3 matrix which, through Hooke's Law, relates stress and strain within a given material. The number of … See more The frequency shift of the incident laser light due to Brillouin scattering is given by where See more • Brillouin scattering • Raman spectroscopy See more
