Claims20
A graded index birefringent component, comprising:
- at least one liquid crystal layer having a plurality of lens segments, each of the lens segments having a plurality of liquid crystal molecules therein, wherein the orientation of the liquid crystal molecules varies across each lens segment of the liquid crystal layer.
A method for manufacturing a graded index birefringent component, the method comprising:
- forming a surface relief element having a plurality of sags therein;
- forming a curable liquid crystal material on the surface relief element;
- applying an electric field across the curable liquid crystal material, wherein the curable liquid crystal material has a plurality of lens segments self aligned with the sags of the surface relief element, and the electric field varies across each lens segment of the curable liquid crystal material;
- and
- curing the curable liquid crystal material to form a liquid crystal layer.
