Résumé

A scanning laser vibrometer and specially developed analysis software were used to systematically investigate the optimal point spacing, and the suitability of measurement quality indicators, such as the residual intensity index, for the two and four point methods. In addition, the sensitivity of the two-transducer to near fields close to sources and discontinuities was examined. The resulting data was analyzed.
