摘要： Methods of reconstructing the surface topography of an object embedded in a scattering medium are provided, with example methodologies including: imaging an object embedded in a signal scattering medium using a scattered signal detector; detecting changes in the magnitude of a plurality of scattered signals obtained from multiple fields of view within the medium; and constructing an image of the surface topography of the object based on said plurality of detected signal magnitude changes. A plurality of system, apparatus, control means, evaluation methods, and materials and components useful for practicing the methods are also disclosed.

摘要： A method of creating three-dimensional borehole data is provided, including illuminating a borehole using collimated beams of electromagnetic radiation; rotating the collimated beams in a sweep of at least 360 degrees; detecting backscattered electromagnetic radiation returned from surfaces of associated illumination planes using electromagnetic radiation sensors; converting detected radiation into a corresponding set of volume image data; analyzing the volume image data using computational visualization processing techniques; and creating a three-dimensional image representative of the volume data. Imaging methodologies include a complete, radial conic-shaped surface while the imaging system remains stationary; a plurality of scans performed while longitudinally moving the imaging system a distance d through the borehole between image capture operations; and a plurality of scans performed while longitudinally moving the imaging system a distance d, where d is a distance less than or equal to the collimated beam thickness, so that adjacent scans partially overlap.
