摘要：

In this paper, the authors present a non-contact 2D speckle vibrometer, which is based on an improved image processing algorithm and realized by a compact and low-cost setup. Starting from the results obtained in a previous paper [1], where we demonstrated the feasibility a method for speckle processing in the assessment velocity along one direction, we extend the study to a 2D sensor by overcoming the limits encountered previously, such as the bandwidth of the sensor and the image processing algorithm. The dynamical sensor performances are defined comparing the results with a Laser Doppler Vibrometer (LDVi). In addition the configuration is further simplified by introducing a low coherence source and a simpler electronic circuit.
