Figure 1-2. 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.
