ENHANCING ACCURACY OF DATA ACQUIRED BY A LASER VIBROMETER IN A FIELD SETTING

摘要

The Laser Doppler Vibrometers (LDVs) have gained increased popularity among researchers and practitioners. However, LDVs suffer from their dependency on the optical properties of the surface and sensitivity to external interference that may be easily controlled in the laboratory environment. Applying an LDV to large structures in field setting poses new challenges. This paper considers the problems that were encountered during the design of an automated damage detection system for the Armored Vehicle Launched Bridge and solutions that were applied to enhance the accuracy of the acquired data.
