Researchers Develop New Virtually Imaged Phased Array-based Brillouin Spectrometer

At a microscopic level, every material contains spontaneous sound waves -- acoustic phonons -- that have properties dependent on the material's mechanical properties. When light interacts with these acoustic phonons, it scatters and acquires a frequency shift related to the material's elastic modulus, a characteristic measure of its ability to resist deformation and stress.
