The opto-electronic platform is the main equipment for aviation reconnaissance. It is a surveillance system with the function of search
recognition orientation and tracking by opto- electronic instruments. It is made up of opto-electronic instruments which are used to get high quality image
and stabilization tracking system to control stabilization and gesture of platform for exact tracking. The opto-electronic platform purpose is to achieve high quality image. Besides the impact of optic system
the image quality of the system is influenced greatly in the vibration environment. The research worked by Zhao peng which demonstrated the affection caused by angular vibration was worse than which caused by line vibration
and what was multiplied direct ratio with plane altitude. So it is necessary to design a new device which could be used widely and has good angular vibration isolation effect. According to the theory of parallelogram
the non-angular vibration device had been designed with spatial links
and the theory of non-angular vibration was analyzed. The three-dimensional model was set with UG
the analysis was done by ADAMS/vibration software. The acceleration and displacement response of the device in each direction was calculated by inspiriting it with sine wave of the acceleration in three directions
and the stiffness and damp were studied. All the work prove the design principle of the device is reasonable
and the device is adopted to keep the platform motion moving horizontally
at the meantime the device is good at isolating vibration in all directions. 2010 SPIE.

Next generation free-space optical communication systems have used fiber-optic technology as the seamless connection between free-space and optical fiber. The full-optical free-space optical communication systems use optical fiber as the receiver to get faster communication speed. The atmospheric turbulence deeply influenced on the optical wave propagated in terrestrial application. As the active receiving area of the full-optical free-space optical communication systems is very small
it is important to research on the atmospheric turbulence effects on the full-optical free-space optical communication system. In this paper
we discuss about both the turbulence-induced intensity fluctuations and the angle-of-arrival effects in full-optical free-space optical communication systems which are used in a few kilometers communication. We gave the numerical results of the atmosphere turbulence effects on the free-space optical communication systems. In order to minimize the atmospheric turbulence influence on the full-optical free-space optical communications system
we also investigate the use of fine tracking system in the communication system. We have set up a full-optical free-space communication system in Tokyo and received useful data from the experiment. We compared the receiving power of the experiment
when the fine tracking system is On and Off. From the experiment results
we can see that the fine tracking system effectively mitigates the atmospheric turbulence and increases the receiving power of the communication system. 2010 IEEE.

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.
