Brillouin scattering spectrometry

Measurements and information. Signal processing allows both time- and frequency-domain information to be obtained depending on the type of specimen studied. In addition, the use of frequency-tunable laser to generate density variations within the sample results in thermal expansion by absorption of light. Compared to spontaneous Brillouin scattering, the SNR in this forced Brillouin spectrometry is substantially enhanced by the generation of coherent phonons within the sample. [Pg.341]
