Abstract

LA MEDIDA DE DENSIDAD DE AREAS IRREGULARMENTE MODELADAS DE UN EJEMPLAR (52) SE LLEVA A CABO UTILIZANDO UNA CAMARA DE VIDEO (54) PARA OBTENER UNA SEÑAL DE IMAGEN DE VIDEO REPRESENTATIVA DE LA INTENSIDAD DE LUZ ASOCIADA AL EJEMPLAR. UN DIGITALIZAODR DE VIDEO DE ALTA VELOCIDAD Y BAJO COSTE (58) CONVIERTE LA SEÑAL DE IMAGEN DE VIDEO A UN FORMATO DIGITAL, QUE UN PROGRAMA DE ORDENADOR INTERACTIVO CONVIERTE EN VALORES DE DENSIDAD OPTICA, QUE SE USAN PARA DETERMINAR LA DENSIDAD NETA DE CADA AREA IRREGULARMENTE MODELADA DENTRO DEL EJEMPLAR.
