Abstract
A simple remote sensing single-particle detection system is described which uses light scattering to determine the size and concentration of scatterers. We report here the initial results obtained from the system. A dual wavelength conformation consisting of an inner trigger beam and outer analysis beam is used to eliminate edge effects of the Gaussian profile of the laser beam. This is achieved without the use of complicated optics, by employing an optical fibre and a chromatically dispersive gradient index (GRIN) rod lens to give the correct optical configuration in the scattering volume.
