Abstract
We report a study on the optical diffraction for light propagation per pendicular to the twist axis in the chiral smectic-C liquid crystal. I n this phase grating mode, we find very unusual intensity and polariza tion features in the diffraction pattern. These observed features can be explained by invoking the theory of anisotropic gratings which take s into account the internal diffractions.
