X-ray colour imaging
Abstract
A prototype X-ray color imaging system has been assembled using the principle of tomog. energy-dispersive diffraction imaging (TEDDI). The new system has been tested using samples of nylon-6, aluminum powder and deer antler bone. Non-destructive three-dimensional images of the test objects have been reconstructed on a 300 μm scale with an assocd. diffraction pattern at each voxel. In addn., the lattice parameters of the polycryst. material present in the sampled voxels have been detd. using full pattern refinement methods. The use of multiple diffracted parallel color X-ray beams has allowed simultaneous spatially resolved data collection across a plane of the sample. This has simplified the sample scan motion and has improved data collection times by a factor scaling with the no. of detector pixels. The TEDDI method is currently limited to thin samples (approx. 1-2 mm) with light atoms owing to the very low detection efficiency of the silicon detector at X-ray energies above 25 keV. We describe how these difficulties can be removed by using semiconductor detectors made from heavier at. material. [on SciFinder(R)]
