Study of Polarization of Laser Radiation Scattered 90 Deg
A qualitative experimental study was undertaken of the effects of spherical particle scattering on the polarization of linearly polarized He-Ne laser beams. Four concentrations of particles (either 0.22- or 0.494- ?m diam) were suspended in filtered, distilled water to serve as the scattering centers. Data representing the effects of volumetric particle concentration, detector acceptance angle, cylindrical scattering volume container diameter, and detector depth are investigated. In general, large diameter particles and high particle concentrations depolarize the incident beam the most. Also, increasing the length of the path traversed by the scattered beam greatly increases the depolarization of the beam.
