ABSTRACT:
A system and method for separating particles is disclosed in which the particles are exposed to a moving light intensity pattern which causes the particles to move a different velocities based on the physical properties of the particles. This system and method allows particles of similar size and shape to be separated based on differences in the particles dielectric properties.
