摘要： An apparatus for obtaining an image of a tooth having at least one light source providing incident light having a first spectral range for obtaining a reflectance image (122) from the tooth and a second spectral range for exciting a fluorescence image (120) from the tooth. A polarizing beamsplitter (18) in the path of the incident light from both sources directs light having a first polarization state toward the tooth and directs light from the tooth having a second polarization state along a return path toward a sensor (68), wherein the second polarization state is orthogonal to the first polarization state. A first lens (22) in the return path directs image-bearing light from the tooth toward the sensor (68), and obtains image data from the portion of the light having the second polarization state. A long-pass filter (15) in the return path attenuates light in the second spectral range.

摘要： A method is disclosed for processing of images to detect dental caries, that includes the following steps. Directing incident light (16) toward a tooth (20), where this light excites a fluorescent emission from the tooth. Obtaining a fluorescence image (35) from the fluorescent light component (19), and obtaining a reflectance image (34) from the back-scattered light (18) from the tooth. Applying a color balance operation to the reflectance image. Removing the specular reflectance components from the color balanced reflectance image (82) to give a back-scattered reflectance image (50). Registering the fluorescent image with the back-scattered reflectance image. Combining the registered fluorescent image (115) with the back-scattered reflectance image to provide a diagnostic image (52).
