ALEXANDRIA, Va., Oct. 26 -- David M. Bloom and Mark C. Peterman, both of Jackson, Wyo., have developed visual display devices.

According to the U.S. Patent & Trademark Office: "Polarization light modulators are based on an interferometric design in which a polarizing beam splitter serves as a polarizer and analyzer. A polarization displacement device shifts orthogonally polarized light beams parallel to the long axis of their elongated cross sections."

An abstract of the invention, released by the Patent Office, said: "Phase shifts are imparted to the orthogonally polarized beams by ...
