Hyperspectral imaging is the collection of electromagnetic spectral information over a 2-dimensional or 3-dimensional space. In general, the electromagnetic range that can be exploited by HSI ranges from visible to long wave infrared (LWIR), but is typically in the short wave IR (SWIR) to mid-IR for detection of organic chemicals. The advantages of HSI include the ability to analyze sample at stand-off distances and over potentially large areas such as battlefields and chemical release plumes. The technology is still maturing, and an expert must perform data interpretation.
