Design And Application Of Scope Anti-Shake System

The anti-shake technology is in the rapid development, the image stabilizing question becomes the international scientific research topic currently that the authors majoring in optics pay attention to. Because of the characteristics of telescopes, image stabilization relies mainly on optical anti-shake devices: using the movable lens to compensate the image deviation; this system has been successfully applied in DC.In this paper, an anti-shake system is designed for small optical telescope, which has a compact size, low power consumption and good anti-shake effect. Firstly, the basic theory and history of image stabilization and the principles of all types of anti-shake technology and features are introduced; the relationship between scope motion and image motion is analyzed; and then the optical anti-shake principles are outlined. Based on all above, the system solution is given and also the design of the lens frame structure and its driver. According to the systems solutions, the system's hardware circuits and software are developed, which meet the requirements of low power consumption and small size, and could work efficiently. The mathematical model of lens control system is affected by driver circuit and uncertainty of the parameters, and they are analyzed in chapter 4 so the new model could be given. And then, the frequency of shaking signal is analyzed, so that the PID controller and robust controller could be developed.
