We present measurements of the scalar-field light scattering of individual dimer, trimer, and tetrahedron shapes among colloidal clusters. By measuring the electric field with quantitative phase imaging at the sample plane and then numerically propagating to the far-field scattering plane, the two-dimensional light-scattering patterns from individual colloidal clusters are effectively and precisely retrieved. The measured scattering patterns are consistent with simulated patterns calculated from the generalized multiparticle Mie solution.
我们呈现了胶体簇中单分子二聚体、三聚体和四面体形状的标量场光散射测量结果。通过在样品平面用定量相位成像测量电场，然后数值传播到远场散射平面，有效地精确地恢复了单个胶体簇的二维光散射模式。测量的散射模式与从广义多粒子 Mie 解计算的模拟模式一致。
