Abstract: We present a simple ‘shift-and-add’ based improvement in the angular resolution of single electron backscatter diffraction (EBSD) patterns. Sub-pixel image registration is used to measure the (sub-pixel) difference in projection parameters for patterns collected within a map, and then the pattern is shifted and added together. The resultant EBSD-pattern is shown to contain more angular information than a long-exposure single pattern, via 2D Fast Fourier Transform (FFT)-based analysis. In particular, this method has the potential to enhance the scope of small compact direct electron detectors (DEDs).
