The quality of a 3D range scan should be independent of the surface
properties of the object. Most active range scanning techniques,
however, assume a diffuse reflector to allow for a robust detection of
incident light patterns. In our approach we embed the object in a
fluorescent liquid, making light rays visible in the volume. This allows
for the acquisition of high quality scans for materials with a wide
range of different reflectance properties, including very dark surfaces,
translucent materials, or even clear glass.
