Spatial filter arrays (SFAs) have attracted great interest because of its wide applications, including coronagraph imaging, nulling interferometer, wavefront controls, wavefront compensation, free-space laser communications, adaptive optics, atmospheric compensation, and synthetic aperture imaging.
The military applications are similar to NASAs. The commercial applications, of this general technology, include low-profile cell phone camera lenses, smart glasses, solar concentrators, eye glasses & ophthalmic goods, night vision goggle lenses, 3D led films, microlens arrays, 3D imaging, CMOS photonics & optical backplanes, endoscopy & medical optical instrumentation, and military optics.
