Multi-band IR data of the space object can be used in the fields of object identification and space surveillance. The radiation characteristics of the object can be obtained by analyzing these data. These characteristics include temperature  area  emissivity  absorptivity  reflectivity  and temporal trends. The infrared radiation temperature of the space object is an important characteristic from which the object's working state in orbit can be judged. We apply the method of measuring the spectral distribution of the object and fit the data to the Planck formula to determine the temperature. In order to improve the precision of measuring temperature on the space object  we optimize the centric wavelength and the bandwidth effectively. Also  we use a simple program to implement temperature measurement. 2010 Copyright SPIE - The International Society for Optical Engineering.

To study the action of shock wave in CH target  one-dimensional grazing incidence KBA microscope for 4.75keV energy was set up. Because of strong absorption in air  4.75keV energy microscope can just work in vacuum. Accordingly  the alignment and assemblage will be very complicated and difficult. A special multilayer method  using double periodic multilayer  was proposed to solve this problem. This multilayer has high reflectivity not only for 4.75keV X-rays but also for 8keV X-rays at the same grazing incidence angle. It means 1D-KBA microscope has the same light trace for different working energies. Therefore  we can implement the alignment and assembly of 4.75keV system by the help of 8keV X-rays. Because 8keV X-rays is very easy produced by X-ray tube and has strong transmittability in air  the alignment and assemblage process became relatively easy. By now  we have finished the alignment experiment at 8keV and obtained imaging results. The performance is about 2-3m resolution in 250m field of view. It is coincide with the calculation. 2009 SPIE.
