The measuring method of the optical activity by the presence of linear birefringence is considered. For the KDP group crystals ($\rm KH_2PO_4$, $\rm NH_4H_2PO_4$, $\rm CsH_2AsO_4$ and $\rm RbH_2PO_4$) the temperature dependence (from 295 K to melting temperatures) of $g_{11}$ components of gyration tensor are obtained.
