Abstract

An apparatus for X-ray measurement, includes an X-ray source, an X-ray detector, an optical inclinometer, and a processor. The X-ray source is configured to generate and direct an X-ray beam to be incident at a grazing angle on a surface of a sample. The X-ray detector is configured to measure X-ray fluorescence emitted from the surface of the sample in response to being excited by the X-ray beam. The optical inclinometer is configured to measure an inclination of the surface of the sample. The processor is configured to calibrate the grazing angle of the X-ray beam based on the measured inclination, and to further fine-tune the grazing angle based on the X-ray fluorescence measured by the X-ray detector.
