Abstract

LA RADIAZIONE DA ANALIZZARE E' INVIATA SU UN ELEMENTO (5) CHE SELEZIONA PARTI DIVERSE DELLO SPETTRO AL VARIARE DELL'ANGOLO D'INCIDENZA DELLA RADIAZIONE. I VALORI D'INTENSITA' DELLA RADIAZIONE USCENTE DALL'ELEMENTO (5) SONO RACCOLTI DA UN'UNITA' DI ACQUISIZIONE ED ELABORAZIONE DATI (9) CHE ELABORA TALI VALORI CONFRONTANDOLI CON LA FUNZIONE DI TRASFERIMENTO DELL'ELEMENTO PER RICAVARE LE INFORMAZIONI SULLO SPETTRO.
