Interferometric Digital Imaging
Abstract
The Illinois Interferometric Imaging Initiative (4Is) demonstrated that aspects of conventional focal imaging, coherence sensing, holography, spectroscopy and tomography could be integrated to obtain revolutionary new functionalities in digital imaging systems. Novel functions demonstrated included multidimensional imaging, phase and polarization sensitive imaging, simultaneous spatial and spectral analysis and nonlocal basis vector sampling. The 4Is initiative provides strong evidence that the 'pixels-to-pupils ratio' problem of distributed sensor systems can be addressed by designing sensors to detect target specific physical primitives. These primitives can be adaptively or interactively identified and isolated. Initiatives to develop scan-free 3D microscopes, spatio-spectral biosensors, advanced tracking telescopes and cooperative sensor arrays have resulted from the 4Is initiative.
