Continuous-scan laser Doppler vibrometry

CSLDV can allow one to capture the mode shapes of a structure with high resolution much more quickly than would be possible with SLDV.

Allen & Sracic[1] show results where measurements were acquired with CSLDV in a hundredth of the time that would be required for LDV.

Allen & Aguilar[2] postulated that the additional detail available from CSLDV might provide important information when validating structural dynamic models.

Speckle noise is difficult to predict, depending on the properties of the surface, the geometry of the structure and position of the LDV,[3] so further research is needed to establish the limits of CSLDV.

Most of the subsequent advances in this area have arisen from the group at Imperial College in London by Stanbridge, Ewins, Martarelli and Di Maio,[5][6][7][8] who coined the term "CSLDV".
