Demonstration of the adaptive scan technique in a real experiment, with 50 ms exposure time at each scan point. (a) The scatter plot displays all scan points (677 in total) measured during the experiment. The subset of dark blue points (140 in total) represents the points of interest acquired through the boundary search algorithm, effectively outlining the complete boundary of the object. The horizontal step size, Sx, and vertical step size, Sy, are both 300 nm. Gaps in the trajectory of the dark blue points correspond to instances when escape jumps are executed. (b) Following the boundary determination, a subsequent scan is performed to measure diffraction patterns exclusively within the established object boundary. In this filling scan, the horizontal step is set at 300 nm, and the vertical step size is set at 1000 nm. This scan yields a total of 446 diffraction patterns within the RoI. (c) Reconstruction of the object utilizing solely the points obtained within the RoI, resulting in a detailed representation of the object.
