| 摘要 |
The present invention relates to a dynamic light scattering measurement device, which is not influenced by disturbance such as vibration, and is not necessary to adjust gap of a light path between a reference light and a sample light. The dynamic light scattering measurement device (1) comprises: an irradiation unit which irradiates light from a low-coherence light source (10) to a sample (40) including particles (42); a spectral intensity acquiring unit which acquires spectral intensity of reflective light, scattered light and interference light by a spectrum of the scattered light from the sample (40) which passes through the reference plane; and a measuring unit which measures the dynamic light scattering of the sample (40) based on the acquired spectral intensity. |
