One strength of this detector is that any combination of the micromirrors can be used to obtain real-space images of the sample by programming different images to the micromirror array. (Note that post-sample lenses are not required to use specific diffraction spots for dark-field imaging with this detector!) When user-specified mirrors are flipped towards the photomultiplier tube, a 'virtual' aperture is created that allows real-space images of the sample to be obtained. For example, when all the mirrors are flipped to the CMOS camera, diffraction patterns of the sample can be recorded. This configuration allows both imaging and diffraction in one system. Regarding detector development, the figure below shows a programmable STEM detector developed at NIST that utilizes a digital micromirror array.

Project activities include development of novel electron detectors and detection schemes, image contrast interpretation, software development to operate instrumentation and interpret results, and proof-of-concept applications to diverse material systems. As a result, more electrons will scatter and the scattering angles will be larger, providing the information-rich content needed to measure crystal phase, crystal orientation, defects, and internal order. A fully analytical STEM-in-SEM has the potential make many powerful TEM-like capabilities available to a large population of SEM users worldwide at a fraction of the cost of conventional higher energy electron microscopes. Decreasing electron energies to those typical of an SEM (~20 keV) reduces the mean free path to values commensurate with the particle size. Electrons with energies of the order of 200 keV exhibit a mean free path for scattering that can easily approach an order of magnitude larger than the structure itself. For example, consider structures in the size regime smaller than 10 nm.
