Light scattering apparatus, light scattering measurement method, light scattering analysis apparatus and the light scattering measurement analysis

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive and practical light scattering apparatus and a light scattering measurement/analysis method for measuring a light scattered by an opaque sample and calculating a photon correlation function from time-series data of photon pulses measured by light scattering.;SOLUTION: A control section 190 controls so as to approximate a length of a light path for making a laser light outputted from a laser light source 210 enter into the sample 110, exit from the sample and be scattered as the scattered light to zero. A detector 330 detects the exiting scattered light, and outputs the photon pulses. A pulse interval measuring instrument 350 measures time intervals of the photon pulses outputted from the detector 330. A calculation section of a computer 360 uses the time intervals of the photon pulses measured by the pulse interval measuring instrument 350, and calculates the n-th order correlation function (n≥1).;COPYRIGHT: (C)2006,JPO&NCIPI
