Design and Function
Optical 3D scanners are used in the dental field to measure
and digitize human jaw models in three dimensions. Using the
"structured-light scanning" principle, a stripe pattern of light is
projected onto an optical mirror, which deflects the test pattern
onto the object which is being measured. The distortion of the light
pattern caused by the depth of the jaw model is registered and
processed by two high-resolution cameras which are mounted on a
tripod together with the mirror, and thus subsequently digitized into
a virtual, three-dimensional model.
