| 中文摘要 | 文章首先介绍了大气视宁度的概念，详细讨论了大气湍流模型以及视宁度参数r0的由来。随后又简要介绍了各种测量大气视宁度的方法和仪器，重点讨论和总结了像运动法的原理和优点，尤其是差分像运动视宁度监测仪(DIMM)在天文选址领域的重要而独特的作用，以及国内和国际上对实现DIMM的自动化观测进行的研究和探索。 本文对可远程控制的DIMM系统进行了详细的描述与总结，包括如何实现导星，图像采集与数据处理部分的实现，实测数据分析以及误差分析等均作了较为详细的说明。随后重点介绍了全自动差分像运动视宁度监测仪（ADIMM）系统的设计方案，包括如何建立ADIMM系统数据库、系统对气象站的要求、如何自动选星、如何自动指向、两级导星的实现、图像采集与数据处理以及测量结果的保存和发布等。 差分像运动视宁度监测仪的自动化研究具有积极的意义和实用价值。例如：南极、西藏等特殊环境地区的选址工作，使用一套自动化DIMM系统就可以大大降低视宁度测量工作的难度；同时自动化DIMM系统也给已选站址的长期实时视宁度监测计划带来了极大的方便，通过对站址的长期视宁度观测不仅可以得到站址的本征视宁度参量，还可以获得站址周日、周月、周年的视宁度变化，为更加合理的安排观测计划、更加有效的利用好望远镜提供科学有力的依据。 |
| 英文摘要 | The concept of the atmospheric seeing was introduced first of all, and then we discussed the model of atmospheric turbulence and the origin of the atmospheric seeing parameter---r0. Many ways and instruments for measuring the atmospheric seeing was introduced briefly, the theory and advantage of the image motion measurement was discussed mainly, especially the Differential Image Motion Monitor plays an very important role in site survey, and the research about the Automated Differential Image Motion Monitor in the world. The system of Remote Control Differential Image Motion Monitor which include guiding star, image acquisition and data process, the result analysis and error analysis was particular introduced. And after that the system of Automation Differential Image Motion Monitor which include how to establish database、the requirement of the weather station、auto-selecting star、auto-pointing star、two-level guiding star、image acquisition and data process、how to save and release the result etc was mainly introduced. The research on Automated Differential Image Motion Monitor is of positive significance and practical utility. For example: Site Survey at Antarctic Pole or Tibet where the atmosphere is terribly vile is a very difficult work, but the ADIMM system can reduce the trouble; Meanwhile the long-term seeing observation for the fixed site will become more convenient with the ADIMM, through the long-term measurements we can get the intrinsic site seeing and the curve chart of seeing dayly、monthly and annual, the latter is helpful for observation plan arrangement and is powerful for improving the utilization rate of the telescope. |
