摘要： A method for classifying a sample based upon a complete spectral analysis. The sample is illuminated with penetrating radiation and an initial complete spectral analysis is performed based on spectral resolution of resonant fluorescence lines emitted at the surface, or within the volume, of the sample. If the initial complete spectral analysis yields the composition of the sample to within acceptable limits, analysis values are output to the user. Otherwise, further analysis, informed by the results if the initial complete spectral analysis, is performed.

摘要： An apparatus for inspecting objects utilizes a fan beam or flood beam to illuminate the inspected region of the object. A modulator, which may take the form of a movable mask, dynamically encodes the beam so that each segment of the inspected region receives varying amounts of radiation according to a predetermined temporal sequence. The resultant signal produced by a backscatter detector or optional transmission detector receiving radiation from the object is decoded to recover spatial information so that an image of the inspected region may be constructed.

摘要： Techniques disclosed herein include systems and methods for identifying counterfeit gold jewelry and other counterfeit gold items. Techniques include determining—using a non-destructive mechanism—whether an item of interest (such as an article represented as true gold) is solid gold or a gold-plated object. Techniques include using an X-ray fluorescence (XRF) analyzer to differentiate true gold from gold plating. The XRF analyzer can distinguish between gold plating and bulk gold material by comparing a ratio of L-alpha and L-beta x-ray lines of gold. The analyzer measures a ratio of intensities of characteristic L-lines of gold using X-ray fluorescence (XRF) spectroscopy. When implemented using an XRF analyzer, the system nondestructively determines whether a test object is made of solid gold/gold alloy or has gold plating only.

摘要： An X-ray fluorescence instrument in which x-rays are directed from a source onto a sample by a focusing element. Fluorescence from the sample is detected by an x-ray detector disposed entirely within a volume “interior” to the focusing element, as defined in the description of the invention. A second focusing element may collect emission by the sample and direct it monochromatically, over a large opening angle, onto the x-ray detector. Methods for applying the instrument, particularly for the quantification of sulfur and other contaminating elements in lubricants and fuel are also provided.
