Patent abstract
An apparatus for obtaining images of a tooth comprises at least one image sensor disposed along an optical axis to take polarized reflectance image and fluorescence image, at least one broadband illumination apparatus for reflectance imaging, and a narrow-band ultraviolet illumination apparatus for fluorescence imaging. In order to remove the specular reflection, one or more polarization elements are disposed along the optical axis. A filter is disposed along the optical axis to block narrow-band ultraviolet light, and a switch for selecting one of the operation modes.
