Popis: Temperature dependences of optical path difference δΔі and the relative changes in thickness δlі/l of TGS crystals doped with L-valine are studied. Temperature dependences of the relative changes in refractive indices δnі/(n–1) are calculated. The anisotropy coefficients of refractive indices Аn–1(Т) and linear expansion Аα(Т) are calculated, and a characteristic minimum of these dependences is found near the phase transition temperature.
