| 摘要在当今社会发展下，研究的发展方向越来越趋于精密化和自动化，全自动的设备越来越得到人们的喜爱。而且在当今的科技发展情况下，光学被应用到了越来越广泛的地方，深入到了科学研究的各个领域之中。激光制导，激光武器，和光纤等等都深入到了人类社会之中。本文研究的传函仪即是应用了光学的知识将光学测量方面的精度提高了一个数量级。通过光学传递函数的引入，以及凭借 MTF来确保结果的准确度，所测得值跟平行光管等原始测量透镜焦距的方法相比，可靠性得到的极大的提高。但是从根本上来看，两种试验方法都是在自准直的基础下来完成后续实验的。26013 毕业论文关键词 全自动 传函仪 光学传递函数 MTF 平行光管 自准直 Title transfer function analyzer Abstract In today's social development under the direction of research become more and more sophisticated and automated, fully automated equipment more and more popular. And in today's science and technology development, optics is applied to the more extensive areas, deep into every field of scientific research. Laser-guided, laser weapons, and fiber, etc. deep into the human society. Transfer function analyzer of this study is the application of knowledge that is the optical precision optical measurements will be improved by an order of magnitude. Accuracy of optical transfer function is introduced, as well as with the MTF to ensure that the results of the measured value is compared with the original method of measuring the focal length of the parallel light tubes, etc., which greatly improves the reliability. But from the fundamental point of view, two test methods are completed follow-up experiments in self-collimation of the foundation down.
