摘要:

散焦成像技术已被用来作为一种诊断,以确定复杂的等离子体中的二元团聚体(二聚体)。准二维等离子体晶体由单分散球和二元团聚体组成,其中团聚颗粒悬浮在球形颗粒下方而不形成垂直对。与球形颗粒不同,二元团聚体的散焦图像显示出不同的,固定/周期性旋转的干涉条纹图案。这一结果对今后复杂等离子体的实验研究具有重要意义。

英文摘要:

A defocusing imaging technique has been used as a diagnostic to identify binary agglomerates (dimers) in complex plasmas. Quasi-two-dimensional plasma crystal consisting of monodisperse spheres and binary agglomerates has been created where the agglomerated particles levitate just below the spherical particles without forming vertical pairs. Unlike spherical particles, the defocused images of binary agglomerates show distinct, stationary/periodically rotating interference fringe patterns. The results can be of fundamental importance for future experiments on complex plasmas.
