Images of diffusing particles

Images from a project on particle diffusion, Kvarnström (1999). The images were obtained with a time interval of 0.02 seconds. Particles in phocus are shown as small distinct black objects, while particles out of phocus are extended, the degree of extension depending on the distance to the phocal plane. An object corresponding to a particle out of phocus is further either white or black in its central part corresponding to the particle being above or below phocus, respectively.
