Caption: Normalized net round-trip gain G s p as a function of pump-signal and idler-signal phase mismatches δ ν p s Ω L and δ ν i s Ω L , respectively, for N = ( π / 2 ) 2 . GVD is neglected, so the AM and PM eigenmodes are decoupled. (a) Gain for AM eigenmodes, (b) gain for PM eigenmodes.

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.
