Abstract
Within the field of spectral imaging, the vast majority of instruments used are scanning devices. Recently, several snapshot spectral imaging systems have become commercially available, providing new functionality for users and opening up the field to a wide array of new applications. A comprehensive survey of the available snapshot technologies is provided, and an attempt has been made to show how the new capabilities of snapshot approaches can be fully utilized.

Single-shot compressive spectral imaging with a dual-disperser architecture

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.
