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.

The strong electromagnetic interference (EMI) generated in high-power TEA C02 laser system mainly comes from main discharge circuit
pulse spark switch and power supply. Such strong EMI causes great damage and interference to the control system based on DSP. In this paper
we present the interference sources and their distribution and propose the methods of anti-interference. Measures for hardware design include weakening transient ground potential difference by using equipotential lines between devices
using signal isolation interface to inhibit the transient ground potential interference
and rational layout
shielding and filtering to the control system. And methods for software design include range-limited filter
self-diagnosis and self-repair for the critical data and anti-interference during abnormal reset. The EMI has been inhibited effectively by the anti-interference method proposed above. The result shows that: the software anti-interference method is as important as the hardware anti-interference method for the control system in a complex environment of strong EMI. 2010 IEEE.
