1 The orthorectified aerial image and 5m DEM of Chiu-Shui River.
2 Schematic diagram of single-prism pulse compressor.
3 Isointensity plot of an oblique spatiotemporal Bessel–Airy wave packet.
4 Normalized linear Stokes vector components demonstrate polarization synthesis.
5 Supplementary epifluorescence collection through a ring of optical fibers. (a) Top: CAD-drawing of a custom fiber-ring holder placed under an objective. Bottom: Closeup view showing the ring-like arrangement of the fiber tips. Only five of eight fibers are shown. Fluorophores are 2-photon excited in the focus of an infrared laser beam (red), causing isotropic fluorescence emission (green). (b) Left: Top view of the ring-like arrangement of eight 1-mm diameter fibers. Right: Dual-channel detection in a custom 2PLSM setup. Optical fibers were bundled and placed in front of a second PMT.

7 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.
