Reconstruction results of a USAF-1951 resolution target located at different depths. a-b Comparisons of the reconstruction results of USAF-1951 resolution target obtained by sLFM and SAsLFM. The raw light-field images were obtained under a 10 × /0.28NA objective with a 15 × 15 scanning trajectory. While the high-resolution range of SAsLFM is comparable to that of sLFM on one side of the native focal plane, it has an obvious extension on the other side. c Zoom-in areas marked by the boxes in a and b. SAsLFM is able to reveal the details that are corrupted in sLFM at the out-of-focus layers. The intensity profiles along the red and orange lines are shown on the bottom. d Resolutions of sLFM and SAsLFM at different axial positions. In a large axial range of ~ 1 mm, SAsLFM preserves finer details than traditional sLFM. Scale bars: 50 μm
