| Popis: | International audience; Interferometric out-of-focus images of freezing droplets are presented, and compared to simultaneous in-focus images. In these experiments, the freezing process is characterized by a breaking of the initial droplet’s glare points into a wide number of neighbor bright spots. The 2D-Fourier transforms of the interferometric patterns show an elliptical contour, with a central spot and eventually symmetric spread spots more or less intense, located around the position of the initial glare points of the liquid droplet (depending on the degree of freezing). |
