Schematic representation of the particle structures, with peak height and area. A: Single cell with uniform content (a), single cell without uniform content (b), and doublet cells with uniform content (c). B: Time course of signals. C: Position of the cells in the height and area profiles. D: A sphere consists of uniformly dispersed small reflectors and has a central part with a slightly different refractive index (see Discussion).
