Abstract

EL INVENTO SE REFIERE A UN PROCESO Y UN DISPOSITIVO DE TRATAMIENTO DE LAS SEÑALES ELECTRICAS QUE PROVIENEN DEL ANALISIS DE UNA LINEA DE IMAGEN SALIDA DE DETECTORES LINEALES TALES QUE UNA BARRETA (20) DE FOTODETECTORES UNIDOS (COMO 7, 8) QUE REALIZAN UN MUESTREO A PASO CONSTANTE. SEGUN EL INVENTO: - SE EFECTUAN K ANALISIS DE LA MISMA LINEA CON UNOS DESFASES LATERALES RESPECTIVOS DE 1/K DEL PASO DE LOS FOTODETECTORES; - SE GENERA UNA SEÑAL SOBREMUESTREADA MULTICRUZANDO LAS K MUESTRAS; Y - SE SOMETE LA SEÑAL SOBREMUESTREADA A UN FILTRADO INVERSO AL FILTRADO INHERENTE AL ALISADO ESPACIAL. SE REDUCE ASI LA DEGRADACION DE LA SEÑAL DEBIDA AL REPLIEGUE DEL ESPECTRO Y AL FILTRADO INHERENTE POR LA INTEGRACION DE LA "LUZ" SOBRE LA SUPERFICIE FOTOSENSIBLE DE LOS FOTODETECTORES.
