Spontaneous Brillouin
scattering is generated through the interaction between the input
light field and the thermally
fluctuating acoustical fields______ .The feature of this effect is that the frequency shift of the
scattering light is dependent on the scattering angle and theacoustic
velocity
______ in
the medium.
