	The lightweight design of the inner framework of the opto-electronic stabilization platform based on finite element analysis (EI CONFERENCE) 会议论文 OAI收割 2011 IEEE 18th International Conference on Industrial Engineering and Engineering Management, IE and EM 2011, September 3, 2011 - September 5, 2011, Changchun, China Zou Q.; Ma H.-L.; Hu Y.; Ding J.-W. 收藏 \| 浏览/下载：28/0 \| 提交时间：2013/03/25 The airborne opto-electronic stabilization platform should have the characteristics of high requirements for stability tracking accuracy and lightweight. In order to verify the rationality of the main load-bearing structure the inner-gimbal finite element analysis was performed. Because of the poor working conditions of the airborne opto-electronic stabilization platform and the wide range of working temperature variation -45 C 60 C according to the actual working environment air-resistance and temperature were added to the loads of the inner-gimbal in analysis. What's more based on the analysis results lightweight design was performed to the initial model and 64.37% of mass was decreased. The remarkable effect was obtained. This research is going to be instructive to design and production of the airborne opto-electronic stabilization platform in the future. 2011 IEEE.
	Dynamic coupling analysis and modeling for stabilized platform of rolling-pitching seeker (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Electric Information and Control Engineering, ICEICE 2011, April 15, 2011 - April 17, 2011, Wuhan, China 作者: Liu H.; Liu H.; Liu H. 收藏 \| 浏览/下载：17/0 \| 提交时间：2013/03/25 Missile's attitude change will be delivered to visual axis through stabilized platform during maneuvering flight and the missile vibration will be an interference source to visual axis stabilization. In order to solve this problem the coupling relationship between missile attitude and visual axis is obtained by Coordinate transformation. When the seeker stably tracks a target the angular velocity of visual axis in inertial space is zero so the relative angular velocity of roll axis and pitch axis can be derived for servo control. According to Oura dynamics equation the dynamic models of roll axis and pitch axis were established and kinetic equations of two axises were obtained. The dynamic models can provide theoretical basis to developing research of servo control system and structural optimization design of stabilized platform. Finally some measures could reduce the dynamic coupling between the framework was given. 2011 IEEE.
	Research on the the device of non-angular vibration for opto-electronic platform (EI CONFERENCE) 会议论文 OAI收割 5th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Smart Structures and Materials in Manufacturing and Testing, April 26, 2010 - April 29, 2010, Dalian, China An Y.; Song C.-P.; Kuang R.-J.; Jin G. 收藏 \| 浏览/下载：32/0 \| 提交时间：2013/03/25 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.
	Far-field focusing of laser beam based on digital image processing techniques (EI CONFERENCE) 会议论文 OAI收割 Optoelectronic Imaging and Multimedia Technology, October 18, 2010 - October 20, 2010, Beijing, China 作者: Zhao S.; Tian Y.-Z.; Liu L.-S.; Guo J.; Zhang H.-Y. 收藏 \| 浏览/下载：28/0 \| 提交时间：2013/03/25 In order to lead the laser beam transmit in the atmosphere convergently an experiment of laser focus at the distance of 450m and 300m has been operated in the outdoor place. The actual manipulations are as follows: Firstly the laser was collimated by a beam expander then the near-parallel laser beam was transmitted with a Galileo telescope system and the distance between the concave lens and the convex lens can be tuned through a precise displacement platform so the focus of the system changed due to the tiny displacement of the concave lens. Secondly the average power of the laser spot can be measured using power meter the power is 47.67mW and the standard deviation is 0.67mW while the focal length is 450m. Thirdly the energy distribution was found through the laser beam analyzer. The spot images were saved using the beam analyzer then the saved image can be processed with Matlab software afterwards. The function named EDGE and Sobel operator was used in the pre-processing of the saved image then method of median filter was used in the course of image de-noising and 53H filter was adopted in the signal analysis. The diameter of laser spot was obtained by the method above the diameter is 5.56mm and the standard deviation is 0.24mm. The spot center excursion is 0.56mm it is 10.43% of the total diameter of the laser spot. At last the key factors of the energy dissipation in the focusing system can be summarized as follows: restriction of the diffraction limit attenuation in the atmosphere geometrical aberration of optical system and the diffraction limit and the geometrical aberration are significant in the three factors above so we can reduce the impact of the both factors during the design of optical system. The reliable referenced data of the system design can be acquired through the primary experiment research. 2010 SPIE.
