    摘要: 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.

    摘要: An intra-oral imaging apparatus having an illumination field generator that forms an illumination beam having a contour fringe projection pattern when receiving light from a first light source and having a substantially uniform illumination field when receiving light from a second light source. A polarizer in the path of the illumination beam has a first polarization transmission axis. A projection lens directs the polarized illumination beam toward a tooth surface and an imaging lens directs at least a portion of the light from the tooth surface along a detection path. A polarization-selective element disposed along the detection path has a second polarization transmission axis. At least one detector obtains image data from the light provided through the polarization-selective element. A control logic processor responds to programmed instructions for alternately energizing the first and second light sources in a sequence and obtaining both contour fringe projection data and color image data.
