Light field microscopy (LFM) is capable of ultrafast tomographic reconstruction using a light field image acquired in a single snapshot. However, the axial resolution of LFM is inferior to its lateral resolution and is non-uniform in the axial direction. A diffraction-assisted light field microscopy (DLFM) method is proposed in this work to achieve resolution enhancement over the conventional LFM...
The recently developed Diffraction-Assisted Image Correlation (DAIC) method (Xia et al. Exp Mech 53(5):755–765, 2013) provides a simple and accurate means for three-dimensional (3D) full-field deformation measurement. In the DAIC method, a test specimen is viewed through a transmission diffraction grating, resulting in multiple diffracted views of the same specimen that encode 3D geometric information...
