Abstract
An aerosol distribution determining system and method are provided. The system includes a set of light emitters for emitting electromagnetic radiation. The system further includes a hyperspectral imaging camera for capturing hyperspectral images of the electromagnetic radiation in an absence of and in a presence of an aerosol distribution. The system also includes a data processing system for determining at least one of a size, a vertical density distribution, and a shape of particles in the aerosol distribution based on a spectral response, an angular distribution, and a polarization of the aerosol distribution derived using the hyperspectral images.
