The image resolution can be improved without increasing the requirement to optical imaging systems' parameters and decreasing the size of CCD pixel by staggered arrays technology
which arranges several CCDs in a specific mode. In this paper
an image super resolution method of improving the image resolution for 1.5 times both in two directions by 4 linear arrays staggered based on this technology is presented
which avoids the large computation in a single time by use of circulation method. This method is proved effective by the digital simulation
and a simulated experiment platform is constructed to test its feasibility. The image resolution is improved for 1.42 times of the unreconstructed image according to the imaging experiment of resolution chart
which is closed to 1.5 times in ideal case. And also
the reconstructed and unreconstructed images are evaluated by the image information entropy
which proves that the reconstructed image contains more information. 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.
