“…Three-dimensional hyperspectral cubes, i.e., (x, y, λ), where λ is the wavelength, can be acquired using pointscan, line-scan, and area-scan methods. A hyperspectral imaging system typically consists of a CCD camera (or an InGaAs camera for the NIR region), an imaging spectroscope, a light source, a sample holding platform, a computer, and related software (Leiva-Valenzuela et al, 2014;Qin et al, 2013;Siedliska et al, 2014;Tao and Peng, 2014). Figure 2 is a schematic of a hyperspectral imaging system.…”
