1. A full-field microscopy method for detection of Brillouin-scattered light, comprising:
(a) illuminating a two-dimensional plane in a sample with interrogating light having a first wavelength;
(b) collecting light emitted from the two-dimensional plane illuminated by the interrogating light, the emitted light comprising Brillouin-scattered light resulting from interaction of the interrogating light with the sample, the Brillouin-scattered light having a second wavelength shifted from the first wavelength;
(c) passing the collected light through a spectrally-selective assembly comprising a gas or vapor illuminated by pumping light; and
(d) detecting, using an electro-optical sensor, light from the spectrally-selective assembly,
wherein the Brillouin-scattered light from multiple points in the two-dimensional plane in the sample is simultaneously detected by the detecting of (d).
