Measurements were made of the polarization and angular distri-bution of 6328 A He-Ne laser light scattered by various latex-sphere hydrosols. Some measurements were compared with Mie theory calculations, and additional calculations were made t o determine the effect on scattering of variation in particle size and index of refraction. Laser and incoherent light scattering patterns are the same. Measure-ments are also given showing the nature of polarization of the scattered light for various types of incident polarization. Results of this work indicate that laser light scattering techniques can be used to obtain useful information on the properties of atmospheric aerosols.
