Abstract

A full-field microscopy method for detection of Brillouin-scattered light includes illuminating a two-dimensional plane in a sample with interrogating light having a first wavelength. Light emitted from the two-dimensional plane can be collected. The emitted light comprises Brillouin-scattered light resulting from interaction of the interrogating light with the sample. The Brillouin-scattered light can have a second wavelength shifted from the first wavelength. The collected light can be passed through a spectrally-selective assembly comprising a gas or vapor illuminated by pumping light. After the spectrally-selective assembly, the Brillouin-scattered light from multiple points in the two-dimensional plane in the sample can be simultaneously detected by an electro-optical sensor. In some embodiments, the spectrally-selective assembly can be altered by changing a wavelength or polarization of the pumping light to allow acquisition of a Brillouin spectrum.
