Abstract
UN MECANISMO PARA PROBAR LA SENSIBILIDAD DE CONTRASTE VISUAL POR EL CUAL EL CONTRASTE ENTRE UN SIMBOLO DE PRUEBA POLARIZADO VECTOGRAFICAMENTE (12,22A) Y UN FONDO DE REFERENCIA (24) PUEDE SER CONTINUAMENTE VARIADO, CAMBIANDO LA DIRECCION DE POLARIZACION (16`) DE UN ANALIZADOR DE POLARIZACION (16), SITUADO A LO LARGO DEL EJE DEL MECANISMO DE PRUEBA (8`). EL INVENTO SE PRACTICA PROPORCIONANDO UN PROYECTOR DE GRAFICOS O UN REFRACTOR CONVENCIONAL CON UN ANALIZADOR ROTATORIO.
