Abstract
Discretely and continuously tunable filers emplying FLC cells are provided. Exemplary discretely tunable filters employ bistable smectic C* FLC cells. Exemplary continuously tunable filters employ smectic A* FLC cells. Single or multiple stage filters are provided. Blocking filters useful for color generation are also provided. The FLC filters provided can be temporally multiplexed.
