Cholesteric liquid crystals possessing a pitch gradient are expected to occur in several circumstances of some interest. It is necessary to investigate a layer’s light-reflection properties in order to confirm this structure and to further study its response to boundary or field conditions. In this article two different models and their solutions are presented.
