Abstract

EN VIAS (5) TRANSPARENTES SE REVISAN LOS ERRORES (17, 26, 28) PRESENTES. ESTOS ERRORES SE EXPLORAN CON PUNTOS D ELUZ SALIENTE. SE CONDUCE LA LUZA QUE ATRAVIESA Y SALE DE LA VIA (5) A UN SISTEMA RECEPTOR (3) QUE PRESENTA UNA ZONA TRANSPARENTE (7) Y UNA ZONA OPACA (8, 8''). EL TRANSFORMADOR (15) FOTOELECTRICO DISPUESTO EN EL RECEPTOR CONDUCE EL IMPULSO CORRESPONDIENTE A LA INTENSIDAD DE LUZ DE CHOQUE CON LA VIA A UN CALCULADOR (6). A TRAVES DE LA EXPLORACION DE LA VIA (5) TRANSPARENTE CON DOS RAYOS DE LUZ (2, 2'') PARALELOS Y ALTERNATIVOS INCIDENTES SOBRE LA VIA TRANSPARENTE PUEDE REVISARSE CON APARATOS SIMILARES EN CAMPOS OSCUROS Y CON TRANSMISIONES DIRECTAS. EL DISPOSITIVO TRANSVERSAL PARA PUNTOS DE LUZ SALIENTES CONSISTE EN UN ESPEJO POLIGONAL (9) GIRATORIO CUYA SUPERFICIE (10) SE ENNEGRECE HASTA LA MITAD, Y EN LA ROTACION SE PRODUCE UNA ZONA (14) TRANSPARENTE CORRESPONDIENTE A LA MITAD DEL ESPEJO Y UNA ZONA 813) ENNEGRECIDA CORRESPONDIENTE A LA OTRA MITAD DEL ESPEJO.
