Paper Abstract

In the present article we report the results of our experiments on the possibilities of using birefringent materials for achieving spatial filtering operations. These filters divide the input spectrum into two orthogonal components and also introduce a phase difference accompanied by a shear, the nature of shear being dependent on the birefringent device used. This fact can be fruitfully utilised for a number of useful purposes, some of which are discussed in the present paper.
