Spectral Imaging encompasses a broad range of techniques for scientific image analysis, the end result of which is the production of both the image as well as the spectral composition of a scene of interest. A review of the typical implementations of spectral imaging is discussed in this article. Particular emphasis is placed on the manner of data acquisition, a distinction that frequently determines the suitability of one technique over another for a given application. Our new Simultaneous Hyperspectral Imaging camera is discussed. Its key feature is the ability to collect all spectral and image data in one shot. This feature makes our camera particularly suited to spectral imaging of dynamic scenes in the field as well as in laboratory and industrial environments.
