Abstract
A new method of measurements of elastic constants of nematic liquid crystal s by applying the nonlinear optical effect is presented. This. method bases on measurements of a value of the reorientation threshold in a liquid crys tal layer while the reorientation is induced by the light beam passing thro ugh the layer. The obtained results are in a qualitative compatibility with the results obtained by classical methods.
