Apparatus and method for caries detection |
| abstract |
An apparatus for imaging a tooth has at least one illumination source for providing an incident light having a first spectral range for obtaining a reflectance image of the tooth and a second spectral range for exciting a fluorescence image of the tooth. A first polarizer having a first polarization axis and a compensator in the path of the incident light of the first spectral range are disposed to direct light toward the tooth. A second polarizer is disposed to direct light obtained from the tooth toward a sensor and has a second polarization axis that is orthogonal to the first polarization axis. A lens is positioned in the return path to direct image-bearing light from the tooth toward the sensor for obtaining image data. A filter in the path of the image-bearing light from the tooth is treated to attenuate light in the second spectral range. |
