摘要：
The use of spatially aligned laser beams of two or more different wavelengths from various spectral ranges is proposed to determine the microscopic displacements for different temperature profiles in the medium where the beams propagate. For certain temperature gradients, numerical simulations are performed. (C) 2002 MAIK "Nauka / Interperiodica".
