In this study, we obtained diffraction-map datasets from mineral samples using a transmission electron microscope (TEM) and a CCD camera to analyze local strains within the samples. From the obtained datasets, quantitative strain maps and diffraction-contrast images by virtual objective apertures with arbitrary shapes were constructed. We applied the methods to in-situ nanoindentation TEM experiments to measure local strain of samples under compression stress.
