Optical vortex analysis has become an important tool in optical metrology. It has been shown to be able to measure small displacements with up to nanometric precision. We analyze optical vortex behavior in dynamic speckle patterns with the boiling phenomenon. We first study translational patterns with boiling and we find the limitations of the optical vortex metrology. Pure boiling patterns are also evaluated and we find a quantitative descriptor for the activity. We also observe that vortices exhibit a Brownian motion in pure boiling patterns. Numerical and experimental results are shown.
光学涡旋分析已成为光学计量学中的一种重要工具。它已被证明能够以高达纳米级的精度测量微小位移。我们分析了具有沸腾现象的动态散斑图案中的光学涡旋行为。我们首先研究了沸腾时的平移图案，并发现了光学涡旋计量学的局限性。还对纯沸腾图案进行了评估，并找到了一个用于描述其活动的定量指标。我们还观察到涡旋在纯沸腾图案中呈现布朗运动。展示了数值和实验结果。
