A grazing incidence x-ray scattering (XRS) method  Order perturbation theory (FOPT)  is stated briefly and an experimental facility based on an improved X-ray diffraction has been introduced  which can work with high performance. The x-ray scattering distributions of two super smooth silicon samples measured at the incidence angle 0.2 degree  as the x-ray wavelength is 0.154 nm  have been given and analyzed by the FOPT to give information about the surface profiles. As a comparison  the root mean square (RMS) surface roughness  grey-scale maps and one-dimensional power spectral density (1D PSD) have been derived from the atomic-force microscope (AFM) data. The results evaluated by FOPT are in good agreement with that of AFM  which indicates that x-ray scattering method is a practical characterization for the investigation of super smooth surfaces. 2011 IEEE.

A soft x-ray reflectometer with laser produced plasma source has been designed  which can work from wavelength 8nm to 30 nm and has high performance. Using the soft x-ray reflectometer above  the scattering light distribution of silicon and zerodur mirrors which have super-smooth surfaces could be measured at different incidence angle and different wavelength. The measurement when the incidence angle is 2 degree and the wavelength is 1 lnm has been given in this paper. A surface scattering theory of soft x-ray grazing incidence optics based on linear system theory and an inverse scattering mathematical model is introduced. The vector scattering theory of soft x-ray scattering also is stated in detail. The scattering data are analyzed by both the methods above respectively to give information about the surface profiles. On the other hand  both the two samples are measured by WYKO surface profiler  and the surface roughness of the silicon and zerodur mirror is 1.3 nm and 1.5nm respectively. The calculated results are in quantitative agreement with those measured by WYKO surface profiler  which indicates that soft x-ray scattering is a very useful tool for the evaluation of highly polished surfaces. But there still some difference among the results of different theory and WYKO  and the possible reasons of such difference have been discussed in detail. 2009 SPIE.

Profile error of super smooth surface of optical elements at X-ray/EUV in synchrotron radiation (SR) light beam line is described as slope error of them generally. The Long Trace Profiler (LPT) is used for testing surface slope error of SR optical elements in world generally. It is requisite to use In-suit LTP measuring surface thermal distortion of SR optical elements with high heat under high bright SR source. Authors design an In-suit LTP by means of co-path interferometer with pencil light beam. The instrument not only can be used for testing slope error of mirrors in Lab. also in situation test the distortion of mirror with high heat load at synchrotron light beam line. The device can be used to test various absolute surface figures of optical elements such as aspherieal  spherical and plane. It is needless standard reference surface. It is named by LTP-III. This paper describes its basic operating principle  optical system  mechanical constructions  DC serve motor control system  array detector  data acquisition system and computer system for controlling and data analysis of LTP-III. The Instrument has advantages of high accuracy  low cost  multifunction and wide application. Length of surface measured of optical element accuracy is 0.04 arcsec.
