Studenteropgave: Fagmodulprojekt


Differential dynamic microscopy (DDM) is an optical technique that can be used
to extract information from dynamic fluid systems. In contrast to light scattering
techniques like DLS (dynamic light scattering), it requires no complex, specialized
equipment. DDM is applied by performing Fourier analysis on images of nanoparticle-
containing solutions, captured with a video camera through a standard laboratory
microscope. In this report, we have applied DDM with aims to determine the wa-
ter content in aqueous glycerol solutions by extracting their diffusion coefficients and
viscosities. We first break down and outline the necessary theory behind DDM, then
provide a method for experimentation and analysis. While we were able to observe
the dynamics of these systems, we were ultimately unable to extract any empirical
information. We conclude that this technique requires further investigations and more
knowledge to effectively extract the desired dynamics.
