Abstract: The method of liquid crystal (LC) helix pitch determination from the critical voltage of transition from a homeotropic orientation to a translation-invariant structure in a nematocholesteric LC mixture is considered. It is shown that, in the case of nonrigid homeotropic boundary conditions under which there is azimuthal degeneracy of the director rotation relative to the normal to the LC layer, the helix pitch determined from the critical voltage can significantly differ from the true value.
