Multimode interference dynamic light scattering [PDF]
Conference on Lasers and Electro-Optics, 2018 When dealing with dynamic scattering systems, being able to collect strong signals while maintaining a high signal-to-noise ratio (SNR) is critical. It is well known that a spatially coherent measurement provides the largest SNR, while a partially coherent one provides better means for proper spatial averaging.

Two tractable models of dynamic light scattering and their application to Fano resonances
Nanophotonics, 2021 We introduce two tractable analytical models to describe dynamic effects at resonant light scattering by subwavelength particles. One of them is based on a generalization of the temporal coupled-mode theory, and the other employs the normal mode approach.

Dynamic light scattering in shear flow [PDF]
Physics of Fluids, 1998 We describe a new dynamic light scattering technique for measuring diffusion in sheared suspensions. It involves a scattering geometry with two crossing laser beams. A detailed analysis of the correlation function of scattered light is given. The viability of our method is demonstrated in an experiment where the effect of Taylor diffusion on the ...

Kobunshi, 1993 チンダル現象として古くから知られている光散乱は主に高分子溶液中の濃度揺らぎによって生起される.動的光散乱法では10-6～1秒の緩和時間を持つ揺らぎを解析することができるので,希薄溶液中の高分子鎖の運動ばかりでなく,分子間相互作用が極めて大きな高分子集合体やゲル中の分子運動も測定対象となる.以下に具体例をあげて解説する.

Structured Light Field Recovery from Dynamic Scattering Media
PhotonicsPerforming light field recovery from diffusing wave is difficult owing to its complex and randomized light behaviors imposed by scatters. The problem becomes even more challenging when a time-varying scattering medium is involved, because, the scattered ...

New Aspects of Polymer Characterization by Dynamic Light Scattering
CHIMIA, 1985 Can macromolecules be seen moving? No doubt, twenty years ago the answer would have been a definite «No». Today we are more inclined to answer positively, assuming we accept the observation of scattered light as a kind of seeing.
