The characterization of artistic and historical surfaces in a wide, fast, low-expense, and noninvasive way is a necessity for the conservation of these cultural assets. Hyperspectral sensors having bands in the visible-near infrared and short-wave infrared (VNIR-SWIR) regions are commonly used for determining the characteristics and properties of many materials (such as soils, minerals, rocks, water, vegetation) because of their ability to provide information in a fast and nondestructive way. Among the existing VNIR-SWIR techniques, field spectroscopy and imaging spectroscopy (remote sensing) have a crucial part in the characterization of different kinds of surfaces. In this work, the potentialities of hyperspectral sensors (working in the range 0.35–2.5 μm) for cultural heritage applications are discussed. The attention is focused both on field spectroscopy as a method for accurate characterization of small, confined, and highly heterogeneous surfaces and on imaging spectrometry obtained through field sensors. A few case studies where both techniques were employed are also reported
