The determination of the state of conservation of historical structures by optical techniques is still not used so widely as it ought to be, and this is clearly reflected also in national norms that make references only to well established techniques such us ultrasound, radar and sonic tests. However, the clear advantages of such techniques, and especially laser based ones like the Scanning Laser Doppler Vibrometry (SLDV), are driving research in this direction.

Abstract
The determination of the state of conservation of historical structures by optical techniques is still not used so widely as it ought to be, and this is clearly reflected also in national norms that make references only to well established techniques such us ultrasound, radar and sonic tests. However, the clear advantages of such techniques, and especially laser based ones like the Scanning Laser Doppler Vibrometry (SLDV), are driving research in this direction. Different case studies will be presented, regarding both laboratory samples and real structures: as regards the field tests, investigations have been conducted in Schwäbisch Gmünd (Holy Cross Minster) and Berlin (Bode and Pergamon Museums), and the potential of SLDV as a monitoring tool for short term structural evaluation will be also presented using sample walls installed at the University of Bologna.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
