Abstract: A polarized Raman Spectrometric system for defining parameters of a polycrystalline material, the system comprises a polarized Raman Spectrometric apparatus, a computer-controlled sample stage for positioning a sample at different locations, and a computer comprising a processor and an associated memory. The polarized Raman Spectrometric apparatus generates signal(s) from either small sized spots at multiple locations on a sample or from an elongated line-shaped points on the sample, and the processor analyzes the signal(s) to define the parameters of said polycrystalline material.

Abstract: Systems and methods are provided for analyzing a biomechanical property of a medium using stimulated Brillouin scattering microscopy. The method can include a first step of applying a probe beam and pulsed pump beam to a target section of the medium, wherein the pump beam interacts with the probe beam to generate at least one acoustic wave in the medium and at least one Brillouin signal is produced as a result of the generated acoustic wave. The method can also include a second step of receiving the produced Brillouin signal and a third step of determining, using a processor and the Brillouin signal, information associated with at least one biomechanical property of the target section.
