- Snapshot_hyperspectral_imaging abstract "Snapshot (or "non-scanning") hyperspectral imaging is a method of capturing hyperspectral images during a single integration time of a detector array, so that no scanning is involved. The lack of moving parts allows snapshot techniques to avoid motion artifacts, but all such instruments require detector arrays with a large number of pixels. Although the first known reference to a snapshot hyperspectral imaging device—the Bowen "image slicer" dates from 1938, the concept did not provide an advantage for most users, due to the limited number of pixels available. With the arrival of large-format detector arrays in the late 1980s and early 1990s, a series of new snapshot hyperspectral imaging techniques were developed to take advantage of the new technology: a method which uses a fiber bundle at the image plane and reformatting the fibers in the opposite end of the bundle to a long line, viewing a scene through a 2D grating and reconstructing the multiplexed data with computed tomography mathematics, the (lenslet-based) integral field spectrograph, a modernized version of Bowen's image slicer. More recently, a number of research groups have attempted to advance the technology in order to create devices capable of commercial use. These newer devices include a multiaperture spectral filter approach, a compressive-sensing based approach using a coded aperture, a microfaceted-mirror-based approach, a generalization of the Lyot filter, and a generalization of the Bayer filter approach to multispectral filtering While snapshot instruments are featured prominently in the research literature, none of these instruments have seen wide adoption in commercial use (i.e. outside the professional astronomical community) due to manufacturing limitations. Thus, their primary venue continues to be astronomical telescopes. One of the main reasons for the popularity of snapshot devices in the astronomical community is that they offer large increases in the light collection capacity of a telescope when performing hyperspectral imaging.".
