Abstract:
A tomographic system for imaging the internal structure of a test specimen, comprising:an areal detector spaced by a first predetermined distance from the test specimen;a source of radiation spaced by a second predetermined distance from the test specimen;a mechanical manipulator for creating selective relative movement between the test specimen and the source;a control for actuating said source at selected relative positions between the source and the test specimen during a single relative translational pass in a first direction between the test specimen and the source, the source producing radiation during each actuation which impinges a selected volume of the test specimen and projects a two dimensional image of the selected volume onto the detector, successive actuations radiating successive selected volumes, wherein at least adjacent selected volumes partially overlap; anda processor for processing the images, the processor reconstructing a selected surface of the test specimen.
