Time-resolved imaging of settling mineral dust aerosols with digital holography
Abstract
A method is described to approximate the 3D form and distribution of mineral dust (MD) aerosol particles based on digital in-line holographic imaging. The concept involves constructing a 3D geometrical hull of a particle defined by image-perimeter curves from a sequence of 2D images. Measuring holograms every ten milliseconds results in a video revealing the flow of the MD particles in 3D. Examples of two MD samples of different mean particle-size are presented.
