1 Schematic diagram of single-prism pulse compressor.
2 Colour “Lena” (a), reconstructed using 51 (b) and 501 (c) independent scans.
3 Transmission spectra through a lattice of periodic gold film perforated with Z-shaped slits with slit widths w 2 = 25 , 50, 100, 150   nm . h = 500   nm , l = 800   nm , s 2 = 450   nm , w 1 = w 3 = 150   nm .
4 Comparison of x-ray images of (a) cartilage on a chicken’s bone and (e) a tomato. The cartilage is shown clearly in (c) the differential phase image compared to (b) the absorption and (d) the scattering images. The inner structure of the tomato can be seen in (h) the scattering image, whereas (f) the absorption and (g) the differential phase images do not show any profiles.
5 Schematic setup of the thin disk laser resonator and the pump module.

7 Sketch of a microroll that can be fabricated by rolling up strained layers. The tube wall represents a three- dimensional metamaterial consisting of a metal–semiconductor superlattice containing quantum wells and metal gratings.
8 Second harmonic generation methods for studying chirality were developed in organic molecules before being applied to metamaterials. In (a), illustration of SHG from supramolecularly ordered chiral helicenes molecules. In (b), illustration of SHG from G-shaped nanostructures, arranged in a chiral unit cell. The incoming light is at 800 nm (near red color) and the detected signal is at 400 nm (near blue color).
9 Normalized intensity (top) and phase (bottom) profiles of some superpositions of Laguerre–Gaussian modes: L G 01 + L G 05 , L G 0 − 5 + L G 05 , and L G 10 + L G 05 (left to right).
10 Comparison of quantitative phase maps with fluorescent assays during an optoinjection experiment: a) phase map and b) propidium iodide fluorescence (optoinjection assay) 5 min after irradiation ; c) phase map and d) Calcein AM fluorescence (viability assay) after 90 min incubation. Two cells were successfully optoinjected - one proved viable (solid arrow) while the other (dashed arrow) was necrotic after 90 min. Note the significant decrease in the optical thickness of the non-viable cell. Scale bars 20 μm.
11 Example of color stripe indexing based on De Bruijn sequence ( k = 5 , n = 3 )  [35].
12 20 × 24 pixel scan of a life-size mannequin at 324 m distance. fSample = 2 GHz, 7 × 106 pulses s−1, 16 ps histogram binning size, pattern length b = 16384 bits, 2 s per-pixel dwell time. Measurement acquired using a shallow-junction SPAD. (a) Close-up photograph of the scene. (b) Segmented surface plot of the scan, including several pixels locking onto background objects.
