A method of non-invasively imaging a dispersion of particles in time and space, where each particle comprises a coating of a fluorescent material over an inert mineral core and the particles range between 0.5 -5 micron diameter, the method comprising illuminating the area of particle dispersion with spectrally selected excitation light of substantially uniform intensity to excite fluorescence, and recording a time series of images of emitted light from the area of dispersion using at least one imaging device such as a camera. The method is used for monitoring environmental transport of pollutants in soil for example. |
