Since there is relative motion between camera and ground target when taking pictures  the target image recorded in recording media is moved and blurred. In order to enhance the imaging quality and resolution of the camera  the image motion had to be compensated. In order to abate the effect of image motion to image quality of space camera and improve the resolution of the camera  the compensation method of image motion to space camera is researched. First  the reason of producing drift angle and adjustment principle are analyzed in this paper. This paper introduce the composition and transmission principle of image motion compensation mechanism. Second  the system adopts 80C31 as controller of drift angle  and adopts stepping motor for actuators  and adopts absolute photoelectric encoder as the drift Angle measuring element. Then the control mathematical model of the image motion compensation mechanism are deduced  and it achieve the closed-loop control of the drift angle position. At the last  this paper analyses the transmission precision of the mechanism. Through the experiment  we measured the actual precision of the image motion compensation mechanism  and compared with the theoretical analysis. There are two major contributions in this paper. First  the traditional image motion compensation mechanism is big volume and quality heavy. This has not fit for the development trend of space camera miniaturization and lightweight. But if reduce the volume and quality of mechanism  it will bring adverse effects for the precision and stiffness of mechanism. For this problem  This paper designed a image motion compensation that have some advantages such as small size  light weight at the same time  high precision  stiffness and so on. This image motion compensation can be applicable to the small optics cameras with high resolution. Second  the traditional mechanism control need to corrected  fitting and iterative for the control formula of mechanism. Only in this way  we can get the optimal control mathematical model. This paper has high precision of the control formula derived. It can achieve the high precision control without fitting  It also simplify the difficulty of control mathematical model establishment. This paper designed the range of adjusting of image motion compensation mechanism between -5 +5. Based on choosing-5  -4  -3  -2  -1  0  +1  +2  +3  +4  +4 as the expectation value of the imaginary drift angle  we get ten groups of the fact data in adjusting drift angle measured. The test results show that the precision of the drift angle control system can be achieved in 1. It can meet the system requirements that the precision of the control system is less than 3'  and it can achieve the high-precision image motion compensation. 2011 SPIE.   The technique of camera scan control based on current loop control (EI CONFERENCE) 会议论文  OAI收割 2011 International Conference on Electronics and Optoelectronics, ICEOE 2011, July 29, 2011 - July 31, 2011, Dalian, China 作者:  Liu Z. 收藏  |  浏览/下载：20/0  |  提交时间：2013/03/25 As the crucial structure of aerial camera  sca reflector is always requested with high performance of control precision  stable running and rapid responding. The paper introduces a kind of method about current loop control system which is based on position and velocity dual-closed loop control system. This method improves effectively the performance of velocity closed loop control system and amplifies the gain of low frequency. The results show applying these control methods  the influence of the torque ripple has decrease 50% and the compensation rate precsion has promoted double. 2011 IEEE.   Analysis of atmospheric pressure and temperature changes on the image quality of aerial camera (EI CONFERENCE) 会议论文  OAI收割 2011 International Conference on Mechatronic Science, Electric Engineering and Computer, MEC 2011, August 19, 2011 - August 22, 2011, Jilin, China Dong B.; Tian H.-Y. 收藏  |  浏览/下载：27/0  |  提交时间：2013/03/25 This paper starts from the study of the aerial camera's work environment  analyzes the temperature and atmosphere pressure changes on aerial camera's imaging quality of influence. Point out that when the altitude of the camera changes  atmospheric pressure and temperature of constant change  so the camera's optical focal surface position changes  thus affecting the image quality of the camera  causing changes in the camera's focal surface optical  and affecting the camera's image quality. Summarize the rules that the temperature and pressure influence the image quality of the camera in aerial environment. Analyze the various environmental conditions on the impact of camera's image quality. For different types of camera  put forward the corresponding convergence compensation method  and provides a reference value to the development of the aerial camera. 2011 IEEE.   SSA based decomposition of tool position trajectory for diamond turning of freeform optical surfaces (EI CONFERENCE) 会议论文  OAI收割 2009 International Conference on Manufacturing Science and Engineering, ICMSE 2009, December 26, 2009 - December 28, 2009, Zhuhai, China 作者:  Liu Q.;  Lin C. 收藏  |  浏览/下载：19/0  |  提交时间：2013/03/25 The radial spiral feed of the tool and the tool nose radius compensation are taken into consideration for the tool position trajectory (TPT) generation in diamond turning of freeform optical surfaces. Using the coarse sampling and the fine interpolation  a novel approach based on singular spectrum analysis (SSA) is presented to decompose the generated TPT into a slowly varying trend and a quickly varying quasi-periodic oscillation. The numerical experiments of the TPT decomposition of toroidal surfaces have been carried out. The results verify that the proposed approach is very effective for the TPT decomposition.

Our strategies of CGH design and fabrication for optical testing are presented  and an experiment demonstrating the compensation results of CGH and null lens is also reported. In order to design complex CGH  software was developed  with which we can design a CGH including three sections: main section for compensating wavefront in null test  alignment section for adjusting the relative position between CGH and interferometer  and fiducial section for projecting fiducial marks around the optics under test. The design result is represented in GDS II format file which could drive a laser-direct-writer- machine to fabricate a photomask. Then  a 1:1 replication process is applied to duplicate the patterns from photomask to a parallel optical substrate whose surface is error better than /60 rms. Finally  an off-axis aspheric surface was tested with CGH and null lens respectively. The test result with CGH (0.019rms) is almost the same as the result with null lens (0.020 rms). This experiment also demonstrated that fiducial marks projected by CGH can be used to guide the alignment of the optics and measurement of its off-axis distance. 2010 Copyright SPIE - The International Society for Optical Engineering.   Study and calibration of azimuth effect in multi-position strap-down north seeking system (EI CONFERENCE) 会议论文  OAI收割 7th World Congress on Intelligent Control and Automation, WCICA'08, June 25, 2008 - June 27, 2008, Chongqing, China 作者:  Wang Z.;  Zhao J.;  Wang Z. 收藏  |  浏览/下载：10/0  |  提交时间：2013/03/25 In order to reduce the influence of azimuth effect in multi-position strap-down north seeking system  its cause of formation is studied based on the precession principle of the dynamically tuned gyro. A detecting system  composed by true north prism  two Leica theodolites and benchmark prism fixed in the strap-down north seeking system  was designed to calibrate the azimuth effect. By two steps  many measurements are gone on in every position to eliminate the random error. According to the homologous between the error and the position  a sinusoid is made a fit as compensate curve after the error of twelve positions is measured. Then the azimuth effect of the arbitrary position can be corrected by the curve. The experiment result shows that the seeking north standard deviation is only 11.77 after compensation  which is considerably less than the 87.75 without correction. 2008 IEEE.
