B. Devaraj et al., FIRST DEMONSTRATION OF LASER COMPUTED-TOMOGRAPHY OF HUMAN TOOTH BY COHERENT DETECTION IMAGING, Electronics Letters, 31(11), 1995, pp. 874-876
The optical heterodyne technique with an argon laser as the source is
used to obtain the first laser tomographic images of an extracted huma
n tooth. The different layers of the internal structure of tooth such
as dentine and pulp cavity can be clearly discerned with submillimetre
resolution.
