Abstract

UN SISTEMA DETECTOR QUE INCLUYE UN DETECTOR (20) QUE TIENE UNA RED (22) DE ELEMENTOS DETECTORES (24), UN POSICIONADOR DEL DETECTOR MOVIL (32) EN EL QUE SE MONTA EL DETECTOR (20), UN PROCESADOR DE SEÑALES (30) QUE CORRIGE PROGRESIVAMENTE LAS INTENSIDADES DE LOS PIXELS DE UN SISTEMA DE SALIDA DEL DETECTOR RELATIVAS A LA FALTA DE UNIFORMIDAD DEL ELEMENTO DETECTOR, UN CORRECTOR ELECTRONICO DE LA POSICION DE LA ESCENA (40) Y UN CONTROLADOR DEL MOVIMIENTO (36) QUE PROPORCIONA UN COMANDO DE MOVIMIENTO (34) AL POSICIONADOR DEL DETECTOR (32) Y TRANSMITE EL CONTENIDO DEL COMANDO DE MOVIMIENTO AL CORRECTOR DE LA POSICION DE LA ESCENA (40). SE EMITE UNA SEÑAL RELATIVA AL SISTEMA DE IMAGENES DESDE DEL DETECTOR (20) AL PROCESADOR DE SEÑALES (30) AL TIEMPO QUE EL POSICIONADOR DEL DETECTOR (32) SE MUEVE DE MANERA CONTROLADA BAJO EL COMANDO DEL CONTROLADOR DEL MOVIMIENTO (36). SE EMITE UNA SEÑAL DE SALIDA COMPENSADA DE FALTA DE UNIFORMIDAD (38) DEL PROCESADOR DE SEÑALES (30) AL CORRECTOR DE LA POSICION DE LA ESCENA (40), EN DONDE LA POSICION DE LA IMAGEN SE CORRIGE PARA EL MOVIMIENTO DEL POSICIONADOR DEL DETECTOR (32). LA SEÑAL DE SALIDA DEL DETECTOR RESULTANTE (44) TIENE LA FALTA DE UNIFORMIDAD SELECTIVAMENTE COMPENSADA DEL ELEMENTO DETECTOR, PERO LOS OBJETOS DEL CAMPO DE VISION DEL DETECTOR (20) NO QUEDAN ELIMINADOS.
