液体泡沫由复杂的气液界面排列组成，形成复杂的折射系统。因此，对泡沫图像的解释一直是一个挑战，并且对光学错觉高度敏感。这些困难可以通过将实验与计算光线跟踪技术相结合来克服，我们对两个对泡沫研究特别感兴趣的系统进行了详细的演示：有序气泡晶体和扩散光源前面的玻璃板之间的单层泡沫的成像。使用3D动画程序(3D Studio Max)和简化的2D光线跟踪模型，我们说明了这些泡沫结构的基本原理，并建立了这些泡沫结构的几何和图像之间的一些基本关系。鼓励实验者根据自己的需要调整这些方法。
Liquid foams consist of complex arrangements of gas/liquid interfaces, which form intricate refractive systems. The interpretation of images of foams has therefore always been a challenge and highly sensitive to optical illusions. These difficulties can be overcome by combining experiments with computational ray-tracing techniques, which we demonstrate in detail for two systems of particular interest to foam research: the imaging of ordered bubble crystals and mono-layers of foams between glass plates in front of a diffusive light source. Using a 3D-animation program (3D Studio Max) and a simplified 2D ray-tracing model, we illustrate the underlying principles and establish some fundamental relationships between the geometry and the images of these foam structures. Experimentalists are encouraged to adapt these methods to their own needs.
