講座內(nèi)容:
In this talk, the introduction of the experimental configuration of the interferometric imaging for droplet sizing (ILIDS) will be addressed firstly, where particles illuminated by a laser beam will be recorded by a camera which contains information about the size and the shape of the particles. As one of the state-of-art topics, interferometric imaging of irregular rough particles when the interferometric images are speckle patterns will be discussed, where the case of ice particles for airborne instrumentation is a typical example. The simulation of the speckle pattern recorded by the camera in interferometric particle imaging set-up, the use of a digital micromirror device (DMD) for experimental studies where the particle shape can be programmed, and the shape reconstruction from the speckle recorded will be discussed as well.
