Light scattering by laser levitated particles.

A new light scattering facility utilizes a laser particle levitation technique to measure the angular distribution of light scattered by solid particles of size range 10-100 microm, over a- range of scattering angles between 16 and 167 degrees . The performance of the facility is illustrated by an excellent match between the observed scattering from a 33 microm-diam sphere and Mie theory prediction.
