Abstract
In this work, we study the optical behaviour of two types of Birefringent Spectral Filter (BSF) built around a set of retarders and polarizers. We use simultaneously, the wellknown Jones and Muller representations to derive the transmitted light. The effects of sheet thickness, optical angles, temperature and wavelength on the optical response are also studied. We pointed out that the orientation of the first sheet retarder in SOLC BSF should be carefully arranged at theta o=(pi/4N). It is expected that SOLC performances should be improved by increased number (N) of involved sheets (N > 6). Moreover, temperature and thickness effects have been estimated around the visible spectral range. It has been found that thin films could be good candidates to produce stable and performant BSF.
