Abstract :
By means of phase-sensitive laser setup the study of detection of thermal microinhomogeneities in fluids is carried out. Presence in liquid medium small-scale unsteady thermal inhomogeneities should be appeared in local variations of an index of refraction. These variations were required to be discovered by laser sounding of a optical cell with a fluid and by registration of frequency-phase fluctuations of laser radiation has been made in water, ethylene glycol, ethanol and toluene.
