Claim:
1. Apparatus, comprising: a sample-support, configured to fixedly retain a sample in a plane comprising an axis, the plane defining first and second regions in space that are separated by the plane; a source-mount, positioned in the first region, and configured to rotate about the axis; an X-ray source positioned in the first region on the source-mount and configured to direct first and second incident beams of X-rays to impinge simultaneously on a common point on the sample at respective first and second angles along respective beam axes that are orthogonal to the axis; a detector-mount positioned in the second region and configured to move in a plane orthogonal to the axis; an X-ray detector positioned in the second region on the detector-mount and configured to receive first and second scattered beams of X-rays transmitted through the sample in response to the first and second incident beams, and to output first and second signals, respectively, in response to the received first and second scattered beams; and a processor, configured to analyze the first and the second signals so as to determine a profile of a surface of the sample.
