Abstract

A technique is described for computing the time-dependent aureole radiance field about a point source in a scattering and absorbing medium. The experimental feasibility of a time-resolved measurement of this field with a narrow field-of-view radiometer is investigated. The proposed method allows the determination of the single-scattering phase function if the optical thickness (product of the direct path length and the scattering coefficient) is smaller than 0.1. If the optical thickness is larger than 0.5, multiple scattering becomes evident and causes increased broadening of the pulse received by the radiometer. Since the aureole is particularly important in the ultraviolet, a numerical simulation of pulse broadening is presented for this spectral region.
