Figure 8
A comparison of the strain and rotation tensors at z = 2.5 nm, as shown in Fig. 7, computed using two different methods. (a) The strain and rotation tensors as computed using equation (20) (Guizar-Sicairos et al., 2011). (b) The strain and rotation tensors as computed by introducing phase offsets and choosing the phase gradient with the minimum value (Hofmann et al., 2020). (c) The difference between the results. The amplitude threshold for the reconstructions is 0.30 and the magnitude of the coordinate axes is 100 nm. |
