Figure 5: Dynamic colour tuning of arbitrary images.
From: Polarization-independent actively tunable colour generation on imprinted plasmonic surfaces
(a–d) Microscope images of a singular Afghan Girl image as a function of applied electric field. Nanostructure periods are chosen so colours match the original photograph at colour tuning saturation, 10 V μm−1. Scale bars (a–d), 100 μm. Defects due to fabrication errors (missing pixels) have been replaced by nearest neighbours. (e) Microscope image at 10 V μm−1 with a × 10 objective showing pixilation of the image. (f–h) SEM images of the sample before fabrication into a liquid crystal cell. The series shows the constituent nanostructure of individual pixels. Scale bars, (e) 20 μm, (f) 10 μm, (g) 5 μm, (h) 150 nm. Copyright Steve McCurry/Magnum Photos. Image rights granted by Magnum Photos New York.
