Abstract

DISPOSITIVO PARA DETERMINAR LA DISTRIBUCION DE DENSIDADES DE UN OBJETIVO. COMPRENDIENDO UNA FUENTE DE RADIACION QUE GENERA UN ESTRECHO HAZ PRIMARIO QUE IRRADIA EL OBJETO, UN DISPOSITIVO DETECTOR DE LA RADIACION DISPERSA PRODUCIDA POR EL HAZ PRIMARIO, UN DISPOSITIVO DE DIAFRAGMA ENTRE EL OBJETO Y EL DETECTOR, DE MODO QUE ESTE ULTIMO MIDA UNA FAMILIA DE VALORES DE LA RADIACION DISPERSA, Y QUE COMPRENDE TAMBIEN UN DISPOSITIVO DE ACCIONAMIENTO PARA DESPLAZAMIENTO DE LA TRAYECTORIA DEL HAZ PRIMARIO A TRAVES DEL OBJETO. LA RECONSTITUCION DE LA DISTRIBUCION DE DENSIDAD DE VALORES DE MEDICION OBTENIDOS SE CONSIGUE POR UN DISPOSITIVO QUE COMPRENDE UNA MEMORIA A LA CUAL SE APLICAN LOS VALORES DE MEDICION DE LA RADIACION DISPERSA, QUE SE PONDERAN CON DIFERENTES FACTORES EN UNA UNIDAD ARITMETICA, ALMACENANDOSE EN OTRA MEMORIA. MEDIANTE CALCULOS EN SUCESIVAS UNIDADES ARITMETICAS SE OBTIENE UNA IMAGEN FINAL QUE ES ALMACENADA EN UNA MEMORIA Y PUEDE SER PRESENTADA. P
