Using the image of comparative literature on the theory and methodology, this paper cards Western image of the ancient Chinese before the Qing Dynasty and analyzes the characteristics of the traditional mode of thinking and collective imagination at the beginning. Then, connecting the above features, it focuses on the image of the United Kingdom in travel notes of the Qing Dynasty and analyzes the role and significance of the travel notes and the officials in the formation of "the image of the United Kingdom" in the Qing Dynasty. That is, travels text is a kind of cultural narrative, Travels with intertexuality completed the social collective imagination. As the Qing Dynasty Construction of the image, officials try to deviate from the traditional Chinese collective imagination. By virtue of British image of self-desire, they state their self-desire and reflect on their own culture.

本文借助了比较文学形象学的理论和方法论，首先梳理了清代前中国人眼中的&西方形象&，分析出中国古人看世界的文化心理和传统思维模式特点，接着结合上述特点解读清代游记中的&英国形象&，并分析出清代游记和清代使官在英国形象生成中的作用和意义：游记文本是一种文化叙事，游记的互文性写作完成清代人对英国的集体想象；清代使官作为形象的建构者，试图背离中国传统的集体想象，他们借助英国形象言说自我的欲望、反思自身的文化。

Open Linear Encoder includes main grating scale and optical encoder head. This optical encoder head includes LED light source, optical detector module, and secondary phase-grating. LED light will pass through the plano-convex lens and produces parallel light. As the parallel light pass through secondary grating, the quadratic image display on the main grating scale. And the Moire interference will be reflected from the main grating scale and detected by optical detector module, as there is a relative shift between the main and secondary grating. From detecting the periodic sinusoidal signal with phase difference 90°, the period represents the grating pitch, using the counter to detect the number of periodic signals to get the displacement, and we can adapt the technology of electron subdivide further to increase the resolution of measurement .

So the technique of uncooled microbolometer infrared imaging has become one of the main points from now on. In the paper uncooled microbolometer infrared imaging system is studied from focal plane character, image dealing and application. The details are in the following: On uncooled microbolometer infrared focal plane aspect: first, the work principle of microbolometer, manufacturing technology of microbolometer infrared focal plane, temperature balance equation of microbolometer detector are analyzed. The performance of microbolometer detector is predicted by model. Second, the infrared focal plane is the core of infrared system, whose quality can determine the performance of the system. It is the precondition that the high quality of every detective unit maintains the qualification of the focal plane. The even degree of detective units has great influence on imaging characters if the other characters of detective units are normal.
