摘要
本文提出了一种基于改进的图像处理算法的非接触式二维散斑振动仪，该振动仪结构紧凑，成本低。从之前的一篇论文(Di Donato et al.(2004))中获得的结果开始，我们展示了一种沿一个方向评估速度的散斑处理方法的可行性，我们通过克服先前遇到的限制，如传感器的带宽和图像处理算法，将研究扩展到二维传感器。通过与激光多普勒测振仪(LDVi)的比较，确定了动态传感器的性能。此外，通过引入低相干源和更简单的电子电路，进一步简化了结构。
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 (Di Donato et al. (2004)), where we demonstrated the feasibility of 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 performance is 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.
