Caption: 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.

Caption: Effect of EOT on spatial information. The central figure shows the input probe beam generated with the DLP before the FWM. The top row shows the entangled images generated by the FWM process before the plasmonic structures, while the lower row shows the entangled images after transduction through the plasmonic structures.

Caption: 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.

Caption: Compressed spiral-scanning measurement and reconstruction of physical 3D object with spiral scanning. (Top row) Subsampled complex-valued hologram data along the spiral path. The magnitude and phase values are represented by the saturation and hue, respectively, as shown in the color wheel of the legend. Undefined hologram pixels are displayed as the gray color. The corresponding numbers of spiral revolutions p, compression ratio M/N, and the reconstruction performance score (SSIM) are shown in Table 1. (Bottom row) The reconstructed image shows the proximal layer in red (z1=870  mm) and the distal layer in blue (z2=1070  mm). Empty space is depicted as white. (Inset) The zoomed-in view of the restored 3D object. Note the high quality of letter “S” down at the 25% compression ratio.
