Backscattering spectroscopy applied to sizing particles in solution

摘要

Optical backscattering spectroscopy offers instrumental advantages over fixed wavelength multiangle scattering measurements. We present results of backscattering spectroscopy of calibrated spherical latex micro particles in aqueous solution when a beam of white light is incident on the sample. From Mie calculations and Fourier analysis, the radius of the particles can be retrieved, both in monomodal (single particle size present) and bimodal (two particle size present) samples.
