Anisotropic two-dimensional scattering. II - Finite depth and refractive index effects
Abstract
A helium-neon laser beam was incident normal to the surface of a finite-depth scattering medium, and the radiant energy emerging normally form the liquid surface was measured as a function of the radial distance from the laser beam. The scattering centers used were high-quality spherical polystyrene particles of 0.261-micron diameter. It is found that the anisotropic nondimensional intensity distribution depends on the asymmetry factor g and, even though the range tested is small, (1-g) appears to be a correlation parameter in anisotropic backscattering from a medium of finite depth. The particle carriers produce very similar results, thus suggesting that the backscattering intensity is insensitive to the index of refraction of the particle carrier.
