摘要:
The attenuation and otheroptical properties of a medium areexploit-ed to measure a thickness of the mediumbetween a sensor and a target surface.Dis-closed herein are various mediums,ar-rangements of hardware, and processingtechniques that can be used to capturethese thickness measurements and obtainthree-dimensional images of the targetsur-face in a variety of imaging contexts. Thisincludes general techniques for imaginginterior/concave surfaces as well asexteri-or/convex surfaces, as well as specificadaptations of these techniques to imagingear canals, human dentition, and so forth.
