1 Illustration on overlapping region selection. (a) One of the adjacent images. The red arrow indicates the direction for searching overlapping region. (b) The other of the adjacent images. (c-d) The adjacent images after overlapping region selection. Here the green dash box represents the pre-determined region used for searching the overlapping region, the green solid box represents the overlapping region, and the yellow dashed box represents the sliding candidate region.
2 CCD arrangement in numerical simulation.
3 (a) Measured signal beam profiles and polarization projections at the OPA output. By slightly detuning the orientation angle from ${\alpha _{\rm WP}} = {28.7}^\circ$ α W P = 28.7 ∘ to $\alpha = {28.9}^\circ$ α = 28.9 ∘ , the OPA crystal is made to function as a quarter-wave plate. (b) The same measurements as in (a), but with compensation for the wave plate effect. Another BBO crystal, identical to the OPA crystal, is placed orthogonally in the seed signal beamline.
4 Wavefront nephogram of the system under 4°C uniform temperature rise load.
5 Reconstructed images taken from different locations (see Visualization 1).
6 Experiments on a 1-bit defocusing projecting measuring system. (a) One of the captured deformed fringe pattern. (b) Original wrapped phase. (c)-(d) Staggered wrapped phases. (e) Fringe order. (f) Reconstructed absolute phase using the traditional phase unwrapping method. (g) Reconstructed absolute phase using the proposed generalized Tri-PU method. (h) Divided tripartite regions of fringe order. (i) Enlarged subimage in (f). (j) Enlarged subimage in (g).
7 Reconstructed wavefronts (left) and errors (right) of the three methods when reconstructing a wavefront containing high spatial frequency information. (a), (b) The FFT method; (c), (d) the LSQ method; (e), (f) the DZF method.
8 Results of optimization constraints. (a) The result of ${f_{1{\rm st}}}$ f 1 s t with a value of 1.15 nm. (b) The result of ${\gamma _g}$ γ g with a value of 1.56 nm.

10 Evolution of the focusing profile of the transmitted wave across the Weyl metacrystal with the incident dipole polarized along the $x$ x direction when the frequency approaches the Weyl frequency.
11 Simulated wide-field FDCD images and chiral SIM images of chiral filaments with different dissymmetry factors controlled by the multiplication factor m. (a-c) Deconvolved wide-field FDCD images with $m$ m  = 1, 10, and 100, respectively. (d-f) Reconstructed chiral SIM images with $m$ m  = 1, 10, and 100, respectively. In this demonstration, $\Delta t$ Δ t  = 1 s and ${I_0}$ I 0  = 50 W/cm2. The color bar indicates the value of the normalized differential fluorescence. Scale bar: 2 μm. The yellow arrows mark an area, which shows resolution improvement in chiral SIM images.
12 Preprocessed DLHM holograms after normalizing (a) with $I_0^2({\vec r})$ I 0 2 ( r → ) and (b) with $I_0^3({\vec r})$ I 0 3 ( r → ). Intensity reconstructions for (c) the $I_0^2({\vec r})$ I 0 2 ( r → ) normalization and (d) the $I_0^3({\vec r})$ I 0 3 ( r → ) normalization. A loss in the diffraction efficiency of the resulting DLHM holograms is found.
