Figure 6
The final output image of the bidirectional scanning method after the re-meshing process, and comparison between the resolution of bidirectional versus unidirectional scanning. (a) The final refined picture after the image reconstruction processing. (b) The internal pixel arrangement for region I in panel (a), showing a uniform distribution with no missed pixels due to motor vibration. (c) The jagged structures in region II in Fig. 5[link](a) caused by motor backlash are also eliminated and the edge becomes smoother. (d) Resolution analysis of the traditional unidirectional scanning image [Fig. 5[link](d)] using the Fourier ring correlation (FRC) method. (e) Resolution analysis of the post-processed bidirectional scanning image [Fig. 6(a)] using the FRC method.
