From: 3D surface morphology imaging of opaque microstructures via light-field microscopy
A series of separately circle, triangle, and square column object 3D morphology reconstruction experiment. (a) SEM image. (b) Top left is the 3D CAD image of these scaffolds. The others are different digital refocused image at different depth from 3.7 μm to 33.7 μm. (c) Top view of 3D reconstructed morphology. (d) Isometric projection view of 3D reconstructed morphology. Rainbow pseudo color is used to illustrate different depth of object with micro-meter scale. (e) The profile of the black-dashed line of part (c) and a comparison with different flat and smoothness parameters (λflat = λsmooth = 1.1: green-dashed line, λflat = λsmooth = 1.2: blue-dashed line, and λflat = λsmooth = 1.5: red-dashed line).
