Abstract

SE PRESENTAN SISTEMAS MEJORADOS PARA LA INSPECCION OPTICA. LOS SISTEMAS MEJORADOS UTILIZAN CAJAS DE CAMARA MODIFICADAS (10) PARA SUMINISTRAR UNA ILUMINACION INCREMENTADA Y MAS UNIFORME DE LOS OBJETOS QUE ESTAN SIENDO INSPECCIONADOS A TRAVES DEL USO DE VENTANAS ILUMINADORAS. EL OBJETIVO DE LAS CAJAS DE CAMARA MEJORADAS ESTA CONTENIDO DENTRO DE UN ALOJAMIENTO SELLADO, AUTOCONTENIDO (12) QUE ESTA SEPARADO DE LA CAMARA PARA EVITAR LA CONTAMINACION POR PARTICULAS DEL OBJETIVO Y SUMINISTRAR UNA FLEXIBILIDAD MEJORADA DURANTE LA INSTALACION DE LAS CAJAS DE CAMARA EN LOS SISTEMAS DE INSPECCION. LA LUZ DE ILUMINACION SE TRANSMITE A LO LARGO DE FIBRAS (62), AL INTERIOR DE UN ILUMINADOR (44) Y A TRAVES DE UNAS VENTANAS (50), QUE ACTUAN COMO GUIAS DE ONDAS, Y SALE COMO RAYOS DE LUZ (64). LA IMAGEN REFLEJADA, EN FORMA DE RAYOS DE LUZ (66) ES CAPTURADA POR ESPEJOS (48) Y REFLEJADA A TRAVES DE VENTANAS (50) HACIA UN PRISMA (36). EL PRISMA TOMA CADA SUBIMAGEN Y LA DIRIGE HACIA UN PUNTO FOCAL CENTRAL, QUE PUEDE PRODUCIRSE EN UN ESPEJO PLEGADO (52) O DIRECTAMENTE EN EL OBJETIVO DE LA CAMARA.
