Abstract

UN APARATO PARA DETERMINAR Y PRESENTAR CARACTERISTICAS SELECCIONADAS DE UNA PELICULA FORMADA SOBRE LA SUPERFICIE DE UNA BANDA DE VIDRIO, INCLUYE UNA CABEZA DE EXPLORACION MONTADA EN UNA PISTA PARA MOVERSE POR ENCIMA DE LA SUPERFICIE DOTADA DE PELICULA DE LA BANDA DE VIDRIO. LA CABEZA DE EXPLORACION TIENE UNA FUENTE DE IMPULSOS LUMINOSOS GENERADOS A PARTIR DE UNA LAMPARA DE TUNGS-TENO Y UN INTERRUPTOR PULSATORIO, FILTRADA PARA SIMULAR LUZ DE DIA Y ENFOCADA SOBRE LA SUPERFICIE DOTADA DE PELICULA. TAMBIEN HAY UNA ESFERA INTEGRADORA MONTADA EN LA CABEZA DE EXPLORACION, CON UNA ABERTURA DE ENTRADA FORMADA EN SU PARED PARA RECOGER UNA PARTE DE LA LUZ QUE ES REFLEJADA DESDE LA SUPERFICIE. DETECTORES OPTICAMENTE FILTRADOS MONTADOS EN ABERTURAS DE DETECTOR FORMADAS EN LA PARED DE LA ESFERA, GENERAN SEÑALES DE SALIDA QUE REPRESENTAN LAS COMPONENTES <Y> Y <Z> DE LA LUZ RECOGIDA EN LA ESCALA TRICROMATICA X, Y, Z DE LA CIE. UN MICROPROCESADOR PROGRAMADO RESPONDE A LAS SEÑALES DE DETECTOR Y A INFORMACIONRELATIVA A LA POSICION DE LA CABEZA DE EXPLORACION CON RESPECTO A LA SUPERFICIE DE LA BANDA DE VIDRIO, PARA GENERAR PRESENTACIONES VISUALES DE CARACTERISTICAS SELECCIONADAS TALES COMO LA REFLECTIVIDAD, B EN LA ESCALA TRICROMATICA CIELAB, Y EL ESPESOR DEL RECUBRIMIENTO, EN FUNCION DE LA POSICION EN QUE EL HAZ LUMINOSO ES REFLEJADO DESDE LA SUPERFICIE PROVISTA DE PELICULA.
