2. There are multiple definitions for the SWIR band expressed in the literature, 1.1-2.5 μm, 1.5-3 μm, etc. The authors prefer the defmition of 1-2.8 μm since it highlights the region typically not covered by Si CCD cameras, infrared film, or thermal imaging systems.
3. LANDSAT 4 and JERS are multispectral satellite systems that provide low spectral resolution and spatial resolution near 15 to 30m with timelines of one or two weeks. Data from these systems provide SWIR imagery data (JERS 1.60-1.71 μm, 2.01-2.12 μm, 2.13-2.25 μm, 2.27-2.40 μm) for remote sensing applications.
4. AVIRIS, TRWIII, and HYDICE are hyperspectral systems that provide high resolution spectral (typically 4 to 20 nm) information.

9. The selection of a PtSi vs. InSb camera for a given application is often a difficult choice given the many competitors and the minor technical differences between the technologies. For SWIR applications, differences between PtSi and InSb cameras may not be as important since imaging conditions are often in high signal conditions. Indoor imaging is probably more influenced by the illumination source and outdoor imaging by the level of available sunlight than camera array technology.
