INFORMAZIONI GENERALI<\/strong><\/p>\n

Le indagini con imaging multibanda comprendono diverse tecniche fotografiche che sfruttano radiazioni a varie lunghezze d\u2019onda, ognuna delle quali permette di avere una serie di informazioni sulla presenza di determinati materiali sulla superficie ottenendo una preliminare caratterizzazione e mappatura dei materiali presenti. Rappresentano lo step iniziale in una campagna diagnostica in quanto permettono di ottenere in modo non-invasivo e rapido, una documentazione dello stato di conservazione di un\u2019opera indirizzando le indagini puntuali o i micro-campionamenti.<\/p>\n

 <\/p>\n

DETTAGLI TECNICI<\/strong><\/p>\n

Le tecniche che si possono effettuare sono:<\/p>\n

\u2022\u00a0\u00a0 visibile in luce diffusa (LV) finalizzata alla documentazione dell\u2019opera e dei suoi dettagli<\/p>\n

\u2022\u00a0\u00a0 <\/span>fluorescenza ultravioletta (UVL) si utilizza principalmente per indagare la presenza di vernici e protettivi, ma anche residui delle missioni per l\u2019oro e interventi di restauro. Inoltre, alcuni pigmenti possiedono una fluorescenza caratteristica che li distingue dagli altri e che ne permette l\u2019identificazione.<\/span><\/p>\n

\u2022\u00a0\u00a0 <\/span>ultravioletto riflesso (UVR) impiegato per evidenziare eventuali interventi di restauro oltre che per la distribuzione spaziale dei pigmenti <\/span><\/p>\n

\u2022\u00a0\u00a0 vicino infrarosso (IR) permette di evidenziare la presenza di un disegno preparatorio, di pentimenti, di ritocchi, <\/span>di firme o altri segni particolari sotto la pellicola pittorica.<\/p>\n

Dalle combinazioni delle riprese nel visibile con l\u2019UV riflesso e con il vicino IR si ottengono rispettivamente le immagini in ultravioletto falso colore (UVfc) e infrarosso falso colore (IRfc).<\/p>\n

Alle tecniche comunemente applicate su opere policrome si affianca la tecnica fotografica che sfrutta l\u2019acquisizione della luminescenza indotta da radiazione visibile (VIL) che permette la caratterizzazione spaziale di alcuni pigmenti come il Blu Egizio, l’Han Blue e l’Han Purple<\/p>\n
