Abstract:
1. A method for imaging a tooth surface using fluorescent imaging with reflectance enhancement, comprising: providing incident white light a first spectral range for obtaining a back-scattered reflectance image from tooth enamel; providing incident light having a second spectral range for exciting a fluorescence emission from the tooth enamel for obtaining a fluorescence image of the tooth surface; directing the incident white light having a first polarization state toward the tooth surface and directing reflected incident white light from the tooth surface having a second polarization state along a return path toward a 2-D digital sensor, wherein the second polarization state is orthogonal to the first polarization state; directing emitted and reflected image-bearing light from the tooth surface along the return path toward the 2-D digital sensor for obtaining image data from the portion of the light having the second polarization state; and attenuating light in the second spectral range along the return path and transmitting light in the first spectral range along the return path.
