Radial Scattering Of A Laser Beam In Anisotropic Scattering Media
Abstract
Experimental and theoretical results are compared for radiation scattered radially from a laser beam in an anisotropic scattering medium. An azimuthally symmetric He-Ne laser beam with Gaussian radial intensity distribution was incident normal to, and at the center of the top surface of, a scattering medium. The bottom and side surfaces of the cylinder containing the scattering medium were black. The scattering medium was composed of double-distilled water and spherical latex particles of uniform size. Radially scattered radiation was measured as a function of depth for two cases: 1) Rayleigh scattering and 2) strong forward anisotropic (Mie) scattering in the single scattering regime. The experimental data compare very well with the theoretical predictions. It is shown that the single scattering approximation holds for optical depths up to 0.4 for scattering media with depth-to-diameter ratios of unity.
