Abstract

UNA LAMPARA ESTROBOSCOPICA, A TRAVES DE UN ESPEJO SEMITRANSPARENTE (2),ILUMINA LA ESTRIA (3) DE UNA TAPA (4) EN LA QUE SE HA APLICADO LA COMPOSICIONDE RELLENO. EN LUGARES DONDE NO EXISTE MASA O COMPOSICION (5) DE RELLENO, LA REFLEXION DE LA LUZ MEDIANTE EL FONDO DE LA ESTRIA SERA SUSTANCIALMENTE SUPERIOR QUE EN EL CASO DE UNA COMPOSICION DE RELLENO (5) PRESENTE. UN VIDEOCAMARA (6) DETECTA LA ESTRIA (5) MEDIANTE LA REFLEXION ATRAVES DEL ESPEJO (2) SEMITRANSPARENTE. SI LA ESTRIA (3) ESTA DE ACUERDO CON LA NORMA RELLENA CON COMPOSICION DE RELLENO (5), EL VIDEOCAMARA (6) DETECTA UNA ESTRIA ANULAR OSCURA. LAS ZONAS QUE CARECEN DE COMPOSICION DE RELLENO PUEDEN DETECTARSE COMO PUNTOS BRILLANTES EN ESTE ANILLO, LO QUE FACILMENTE PUEDE DETECTARSE POR MEDIO DE LAS ACTUALES TECNICAS PARA TRATAMIENTO DE IMAGENES.LA DIRECCION DE LA REFLEXION DE LA LUZ DEPENDE DE LA POSICION ANGULAR DE LA SUPERFICIE DE REFLEXION. DEBIDO A QUE LA REFLEXION DE LA LUZ DIRECTAMENTE EMANANTE DE LA LAMPARA (1) DESDE EL LADO INTERNO DE LA ESTRIA (3)SE DIRIGE EN UNA DIRECCION FUERA DEL ANGULO DE VISION DE LA CAMARA, NO SE DETECTA ALLI LA FALTA DE LA COMPOSICION DE RELLENO. MEDIANTE LA ILUMINACION DE LA CITADA SUPERFICIE DESDE OTRA DIRECCION, POR MEDIO DE UN ESPEJO (7)CILINDRICO, EL AREA MENCIONADA, EN ESTE CASO DE FALTA DE COMPOSICION DE RELLENO,(5) SE REFLEJARA TAMBIEN EN LA DIRECCION DE LA CAMARA (6).
