DYNAMIC LIGHT-SCATTERING MEASURING DEVICE USING LOW-COHERENCE LIGHT SOURCE AND METHOD OF MEASURING LIGHT-SCATTERING INTENSITY

摘要

PROBLEM TO BE SOLVED: To achieve dynamic light-scattering measurement for realizing measurement (measurement of a grain size, its aggregate state, or the like) relating to a highly precise grain size in a solution containing high-concentration fine particle containing minute particles, and also to provide a method of measuring dynamic light scattering.;SOLUTION: A dynamic light-scattering measuring device has: a Mach-Zehnder interferometer; and a low-coherence light source. Also provided is a method of measuring light-scattering intensity of particles in a medium measured by light emitted from a low-coherence light source by using the measurement method of dynamic light-scattering by the Mach-Zehnder interferometer.;COPYRIGHT: (C)2011,JPO&INPIT
