Abstract Light scattering has been a subject of enduring scientific interest for a long time. An important application of light scattering concerns the role that aerosols play in affecting our climate. We built our own setup to determine scattering matrix elements from irregularly shape particles. The novelty of our experimental apparatus is using photodiode arrays to detect simultaneously at many angles. We also use some angles that quite small which is necessary for accurate characterization of large particles. We tested our setup with water droplets from a nebulizer. Here, we present measurements from soot particles produced from homemade burner. We apply q-space analysis which provides a comprehensive description of scattering in terms of power laws with quantifiable exponents.
