We develop and describe analytically a torsion method for measuring piezooptic coefficients associated with shear stresses. It is shown that the method enables to increase significantly the accuracy of determination of piezooptic coefficients. The method and the appropriate apparatus are verified experimentally on the example of LiNbO 3 crystals. (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
