Light polarizing composition
First Claim
1. A LIGHT POLARIZING SHEET OF THE TYPE WHICH RESOLVES A BEAM OF INCIDENT LIGHT INTO TWO COMPONENTS WHICH EMERGE FROM THE SHEET AS POLARIZED BEAMS WITH THE PLANES OF POLARIZATION SUBSTANTIALLY 90 DEGREES TO EACH OTHER, ONE OF SAID BEAMS EMERGING AS A DIFFUSED BEAM, THE OTHER AS A NONDIFFUSED BEAM, SAID SHEET COMPRISING A CONTINUOUS BODY OF A TRANSPARENT ISOTROPIC MATERIAL AND FIBERS OF A TRANSPARENT POLYMERIC MATERIAL HAVING THE POLYMER MOLECULES THEREOF ORIENTED IN PARALLELISM TO PRODUCE A BIREFRINGENCE OF AT LEAST 0.05 EMBEDDED THEREIN WITH SAID FIBERS SUBSTANTIALLY PARALLEL TO EACH OTHER, SAID ISOTROPIC MATERIAL HAVING A REFRACTIVE INDEX SUBSTANTIALLY IDENTICAL WITH THE REFRACTIVE INDEX FOR THE ORDINARY RAY OF SAID BIREFRIGENT POLYMERIC MATERIAL.
