A researcher has developed curved night-vision goggles using germanium nanomembranes. It has a curved surface that allows a wider field of view for pilots. They solved a background noise problem.
Another DOD project for the same researcher is development of imagers for military surveillance that span multiple spectra, combining infrared and visible light into a single image. They will use a heterogeneous semiconductor nanomembrane, stacking the two incompatible materials in each pixel of the new imager to layer IR and visible images on top of one another in a single image.
