PURPOSE:To give the modulation of a constant period to a spectral wavelength and to perform the experiments of X-ray diffraction, scattering, absorption by a phase sensitive detecting method with high accuracy, by adding a minute rotation vibrating apparatus to an X-ray spectral crystal. CONSTITUTION:Continuous X-ray radiated from an X-ray source 11 are irradiated to a sample 13 to be measured after making incident to a spectral crystal minute rotation vibrating apparatus 12 which is in rotary oscillation at an angle frequency omega and giving wavelength modulation. Further, X-rays diffracted or scattered by the sample 13 or transmitted the sample 13, are detected by an X-ray detector 14. The output of the detector 14 is measured by a phase sensitive detector 15 using the output of a minute rotation driving source 16 as a reference signal. Hereby, X-ray diffraction and scattering or absorption spectrum by the sample 13 is measured with a good ratio of signal vs noise. |
