TL;DR: A single disperser spectral imager is presented that exploits recent theoretical work in the area of compressed sensing to achieve snapshot spectral imaging and can be used to capture spatiospectral information of a scene that consists of two balls illuminated by different light sources.

TL;DR: A single-shot spectral imaging approach based on the concept of compressive sensing with primary features of two dispersive elements, arranged in opposition and surrounding a binary-valued aperture code, which results in easily-controllable, spatially-varying, spectral filter functions with narrow features.

TL;DR: The remarkable advantage of CASSI is that the entire data cube is sensed with just a few FPA measurements and, in some cases, with as little as a single FPA shot.

TL;DR: By leveraging metamaterials and compressive imaging, a low-profile aperture capable of microwave imaging without lenses, moving parts, or phase shifters is demonstrated and allows image compression to be performed on the physical hardware layer rather than in the postprocessing stage, thus averting the detector, storage, and transmission costs associated with full diffraction-limited sampling of a scene.

TL;DR: The capabilities of photorefractive crystals as media for holographic interconnections in neural networks are examined and optical architectures for implementing various neural schemes are described.
