Abstract
An intra-oral imaging system that produces images of a dental surface includes a probe that contains an optical conduit for transmitting light with spatially varying wavelengths for illuminating a dental surface and a camera for receiving light rays reflected from the dental surface. The invention also includes a concave reflector used in conjunction with the probe to increase the field-of-view of the camera, allowing optical coverage of the entire surface of a tooth in a single image.
