Liquid-crystal shells rendered using our method. The shells are formed when a spherical liquid-crystal droplet suspended in liquid is injected with an optically isotropic liquid (see figure 9 in the paper for an illustration of the geometry). The imaging is performed by passing linearly polarized light, emitted from a source at −𝑦, through the shell and then through a polarizer oriented perpendicular to the source polarization (“cross polarized” light) and finally captured by a camera located at +𝑦. The orientation of the polarizers is depicted in the bottom left corner of the figures. The shells were illuminated using blue (480 nm), green (580 nm), red (630 nm) and white (illuminant E) light. The artefacts around the left and right edges of the rendered shells are numerical errors. See the paper for a comparison with captured micrograph photos of the same liquid-crystal shells.
