<p>PROBLEM TO BE SOLVED: To provide a dynamic light scattering measuring device capable of measuring a dynamic characteristic of a highly concentrated medium based on scattered light from the medium by composing an interferometer by using a low coherence light source and limiting scattering volume. SOLUTION: The dynamic light scattering measuring device is provided with the low coherence light source 2, an objective lens 6 irradiating light condensed from the low coherence light source 2 on a solution, a photodetector 9 measuring scattered light intensity of particles by using a Michelson interferometer, and a spectrum analyzer 10 analyzing a distribution of diffusion coefficients of the particles on the basis of the measured scattered light intensity. Since an interferometer with the low coherence light source 2 is used, only scattered light components from a particular portion substantially equal to an optical path length of light source light is detected.</p> |
