The image sets possible under each of the illumination conditions discussed and the two categories into which they fall: reflected radiation images and emitted radiation (luminescence) images. i. Reflected images For reflected images, the wavelength range of the incoming radiation and that of the outgoing radiation is the same. The following types of images are the most commonly used reflected images, but other ranges can be explored. Visible-reflected (VIS) images correspond to standard photography and record the reflected light in the visible region (400-700 nm) from a subject when this is illuminated with visible light. This image is collected in the range in which the object is usually observed and can thus serve as the reference point to interpret the other image sets. Version No. 1.0 Date : 14/10/2013
