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.
