| Abstract: | In the courses of adjusting and observing for DCMT, the image position variation with temperature was found. In this paper, the position variation of each image, which is related to the variation of optical system, are discussed. Based on the analyses of the data for several durations, we found that the linear relationship obviously exists between the position of each image and the temperature, meanwhile, the variation of each part of the optical system with the temperature is calculated quantitatively, thereby a suggcrtion of improving the design of optical system is put forward. |
