August 1, 2008
A matrix laser Doppler vibrometer (MX LDV) can simultaneously measure vibration
of a surface in a 2D array of 16x16 points in a square matrix. The system preserves
the relative phase information between measurement points due to parallel measurement
on all channels. Simultaneous vibration measurement at all points makes it possible
to obtain a 3D deformation shape of the target at any selected time and in any selected
frequency band. The system can be used for studying non-stationary vibrations. |
