X-ray diffraction imaging (XRDI, also known as X-ray topography) is used to image crystalline defects in otherwise perfect (or near perfect) substrates. Using the virtual slits on the QC-RT it is possible to image the sample in modes to visualise scratches, dislocations and other defects, but also to image orientation contrast within the substrate.
These images are created from the same data and allow different long and short range characteristics to be imaged with different processing.
