Abstract

UN ESPECTOMETRO CON MATRIZ DE FOTODIODOS COMPRENDE UNA SERIE ORDENADA (40) DE ELEMENTOS FOTOSENSITIVOS PARA RECIBIR UN RAYO DE LUZ. LA LUZ QUE INCIDE SOBRE UN FOTODIODO OCASIONA DESCARGAS DEL CAPACITOR ASOCIADO. LOS CAPACITORES SE RECARGAN PERIODICAMENETE MEDIANTE UN AMPLIFICADOR DE CARGA A TRAVES DE UNA LINEA (30) DE VIDEO CERRANDO INTERRUPTORES (SW1,.., SW 768) DE TRANSFERENCIA, ASOCIADOS CON LOS ELEMENTOS FOTOSENSITIVOS, RESPECTIVAMENTE. LOS INTERRUPTORES ESTAN AGRUPADOS JUNTOS EN VARIOS SEGMENTOS, LOS CUALES SON DIRECCIONABLES DE MODO TAL QUE DURANTE UNA EXPLORACION DE RECARGA SOLO SELECCIONADOS GRUPOS DE FOTODIODOS SON RECARGADOS. LA INFORMACION SOBRE CUALES SEGMENTOS VAN A SER ACTIVADOS,P.EJ QUE GRUPOS DE INTERRUPTORES SE VAN A CERRAR, ESTA CONTENIDA EN UN BLOQUE (43) DE CONTROL DE SEGMENTO. UN BLOQUE (46) DE CONTROL DE INTEGRACION PERMITE ADICIONALMENTE AJUSTAR LOS INTERVALOS DE TIEMPO ENTRE SUCESIVOS CICLOS DE RECARGA SEPARADAMENTE PARA CADA SEGMENTO SELECCIONADO. LA INVENCION PERMITE SELECCIONAR REGIONES DE LA MATRIZ DE FOTODIODOS PARA UNA APLICACION ESPECIFICA, YA QUE OTRAS REGIONES SE IGNORAN PARA ESA APLICACION, CONDUCE A LA REDUCCION DE LA TASA DE DATOS CON ALTA RESOLUCION ESPECTRAL Y SENSITIVIDAD.
