My current research in metrology development is based around exploring the design and function of the aberration-corrected scanning transmission electron microscope (STEM), to improve the analysis of atomic-resolution annular dark-field (ADF) data and EELS and EDX chemical mapping. Themes include ADF normalisation by detector efficiency, correction of scan-noise and scan-distortion and correction of artefacts in EELS spectra. As part of this research, a series of image analysis and processing codes have been written to inspect, improve and quantify atomic-resolution ADF STEM data.
Combined non-rigid registration & template-matching for low dose-rate high-precision imaging.
The default colormap in Digital Micrograph is greyscale, but different applications or communities ofter use other colour look-up tables (CLUT) to highlight certain features or present data more artistically. You can see your colour scale choices in DM by right-clicking on an image and selecting “ImageDisplay…” or by pressing ctrl+D, then selecting ‘Display’ > ‘Color’, you will see something like this:
