Abstract: An apparatus is provided for performing photothermal measurements on a object. The apparatus, which may be provided as a handpiece, houses optical components including a laser, an infrared detector, a dichroic beamsplitter, and focusing and beam directing optics for the delivery of a laser beam to, and the collection of photothermal radiation from, a measured object. Some of the optical components may be provided on an optical bench that is directly attached to a thermally conductive tip portion for the passive heat sinking of internal optical components. The apparatus may further include a sampling optical element and a photodetector for the detection of luminescence, and a camera for obtaining an image of the object during a diagnostic procedure. The apparatus may be employed for the scanning of a tooth to determine an oral health status of the tooth.

Abstract: There is provided a high-spatial-resolution dynamic diagnostic instrument which can provide simultaneous measurements of laser-induced frequency-domain infrared photothermal radiometric and alternating-current (ac) modulated luminescence signals from defects, demineralization, remineralization and caries in teeth intraorally. The emphasis is on the abilities of this instrument to approach important problems such as the detection, diagnosis and ongoing monitoring of carious lesions and or defects on the occlusal pits and fissures, smooth surfaces and interproximal areas between teeth which normally go undetected by x-ray radiographs or visual examination. The instrument is also able to detect early areas of demineralized tooth and or areas of remineralized tooth as well as defects along the margins of restorations. This capability of inspecting a local spot can be extended to a modulated imaging of sub-surface of target tooth by using a multi-array infrared camera. Two configurations of the instrument are presented.
