Many physics processes underlying phenomena in atmospheric optics happen on a rather short time scale such that neither the human eye nor video cameras are able to analyze the details. We report applications of high-speed imaging of laboratory experiments in atmospheric optics with subsequent slow motion analysis. The potential to study respective transient effects is investigated in general and for a few phenomena in detail, in particular for rainbow scattering due to single oscillating droplets during free fall, and for light propagation effects through atmospheric paths with turbulences, leading, e.g., to scintillation of stars or shimmering of mirage images.
大气光学现象背后的许多物理过程发生的时间尺度相当短，以至于人眼和摄像机都无法分析其细节。我们报告了对大气光学实验室实验进行高速成像并随后进行慢动作分析的应用。一般来说，我们研究了研究各自瞬态效应的潜力，并详细研究了一些现象，特别是自由下落过程中单个振荡液滴引起的彩虹散射，以及光通过有湍流的大气路径的传播效应，例如导致恒星闪烁或海市蜃楼图像的闪烁。
