Figure 1 | Schematic illustration of the fast-switchable optical spatial differentiation based on a reconfigurable FLC chiral nanostructure. a, The FLC chiral nanostructure without external electric field, inset: the local cross-sectional diagram. b, 2nd-order differentiation under +5 V, inset: the local cross-sectional diagram of the helix-suppressed FLC nanostructure, with the molecules rotating to one side. c, Bright-field imaging under -5 V, inset: the local cross-sectional diagram of the helix-suppressed FLC nanostructure, with the molecules rotating the other side. The blue ellipsoid represents the unit director of FLC. The gray cone denotes the helical cone. The blue plane represents the smectic layer of FLC. The gray spring illustrates the chiral structure. The red double-ended arrow designates the polarization direction of the polarizer or analyzer.
