Abstract

PLACAS REFLECTANTES EN MULTIPLES DIRECCIONES. LA SUPERFICIE SUPERIOR DE INCIDENCIA DE LA LUZ (4A, 4B) TIENE FORMA DE CUADRADOS, MIENTRAS QUE LA SUPERFICIE DE REFLEXION (DE PUNTOS) PRESENTA FORMA OCTOGONAL Y CUADRADA, PERO COINCIDIENDO SIEMPRE LOS EJES DE SIMETRIA (6, 7) DE LAS SUPERFICIES SUPERIORES E INFERIORES. LA SUPERFICIE REFLECTANTE INFERIOR ES DE PLATA O ALUMINIO Y EL RESTO ES DE UN MATERIAL PLASTICO TRANSPARENTE. SI VIEDEMOS LAS SUPERFICIES SEGUN LA SECCION (A, A''), APARECERIAN CURVADAS, CON LO QUE EL RAYO INCIDENTE Y EL RAYO REFLEJADO SON PARALELOS, LO QUE PERMITE LA REFLEXION SEGUN MULTIPLES DIRECCIONES. SE OFRECEN DISTINTAS ALTERNATIVAS EN LA FORMA Y TAMAÑO DE LA SUPERFICIES DE INCIDENCIA Y DE REFLEXION.
