At this stage, it is important to point out that the unconventional scan patterns used here induce a paradigm shift in how image data are considered. In a traditional scanning mode, the data are essentially stored as an array of intensities, which are assigned to elements within a 2D matrix. However, for more … See more A typical STEM image acquired using the conventional raster scan path with a dwell time of 20 μs and 512 × 512 frame size is shown in Fig. 1a. Here, the brighter … See more An obvious improvement over the sawtooth scan to avoid a flyback delay is to perform a ‘serpentine’ scan, alternately moving the probe from left to right on one … See more We now focus on smooth curves that can fill the 2D space without crossing themselves.
