在空气/水界面处的磷脂单层的反射中的漫射光散射的成像已经揭示了先前未检测到的单层分离成两个可通过其散射的强度区分的区域。在凝聚相的L-二棕榈酰磷脂酰胆碱的单层中，手性形状的域被覆盖约一半单层的较亮区域包围。虽然从这两个区域的散射强度增加与表面压力的方式一致的热诱导毛细波散射，从更明亮的区域的额外的散射表明叠加在热粗糙度的静态表面粗糙度。
Imaging of diffuse light scattering in reflection from a phospholipid monolayer at the air/water interface has revealed a previously undetected separation of the monolayer into two regions distinguishable by the intensity of their scattering. In monolayers of L-dipalmitoyl phosphatidylcholine in the condensed phase, chiral-shaped domains are surrounded by a brighter region that covers approximately half the monolayer. While the scattered intensity from both regions increases with surface pressure in a manner consistent with scattering from thermally induced capillary waves, the additional scattering from the brighter region indicates a static surface roughness superimposed on the thermal roughness.
