Summary
The ability of an infra-red scanner to detect oil spills over the sea surface is discussed on the basis of the first results of the Archimedes experiment 1983. During this experiment an infra-red scanner was flown over two oil spills and a real-time detection was achieved. The IR images were also recorded and processed in order to improve the film-thickness evaluation. An infra-red visible package was then developed which allows a real-time remote sensing of oil spills, eventually from small aircrafts.
Riassunto
In questo lavoro è indagata la possibilità di individuare chiazze di idrocarburi sulla superficie marina per mezzo di radiometri in infrarosso. L'indagine è effettuata sulla base dei primi risultati dell'esperimento Archimedes 1983. Durante tale esperimento è stato fatto volare un radiometro a scansione in infrarosso, ottenendo l'individuazione in tempo reale di due chiazze di idrocarburi. Le immagini all'infrarosso sono state registrate e successivamente elaborate al calcolatore per migliorare la valutazione dello spessore del film. Sulla base dell'esperienza fatta è stato sviluppato un sistema compatto infrarosso/visibile per l'individuazione in tempo rale di chiazze di idrocarburi, anche da piccoli aerei.
