It is shown, that the T-violating rotation of the photon polarization plane appear under diffraction in a noncenter symmetrical diffraction grating. The rotation angle gives rise sharply, when the conditions of the photon resonance transmission are satisfied.16 pages, 3 figures, uses article.sty, submitted to Journal of Physics BHigh Energy Physics - Phenomenologytext
