Determination of Optical Properties by Inversion of Multiple Scattering Data: Experimental Program
Abstract
An experimental study designed to test the effectiveness of a time dependent inverse radiative transfer algorithm for determining the single scatter properties of optically thick media is described. The inversion algorithm required measurements of the time resolved backscattered radiance following ultrafast pulsed illumination of model, optically thick, atmospheres. Most of the measurements were accomplished with 532 nm, 35 ps duration pulses from a frequency doubled, passively mode locked Nd:YAG laser and a 10 ps resolution streak camera. The last series of measurements were made with a synchroscan streak camera and 5 ps duration pulses from a dye laser synchronously pumped with an acoustooptically modelocked Argon ion laser. The experimental data were analyzed under a companion project Determination of Optical Properties by Inversion of Multiple Scattering Data: Analytic Program. It was shown that it is possible to estimate the single scatter albedo of weakly absorbing particles with a relative error of less than 1%. Keywords: Multiple scattering; Radiative transfer; Inverse scattering.
