اندازه گیری تابع پراکندگی فازی ناشی از هیدروسل ها و آئروسل ها به روش تجربی

When light traverses a medium of scatters with appreciable dimensions, as compare to the wavelength, mie scattering occurs. Measurements of the angular profile of light scattering are very useful for obtaining a detailed characterization of the light scattering mechanisms. We generated a steam of water under laboratory conditions by heating water then measure the intensity of scattered laser light thought the steam with photodiode in various angles. Therefore with this Measuring and having background light, we can estimate scattering phase function from particles. Consequently this method can be used to determine the particle size of liquid or steam matters.
