Abstract: The dome temperature of one telescope influences the image quality of the telescope. This phenomenon is called the dome seeing. In order to detect dome temperature micro-changes, this paper designs the data acquisition system of turbulence fluctuation measurement based on SD card.It can be used to detect the small temperature changes in the telescope dome. The experimental results show that the acquisition system can collect a lot of data through multichannels at anytime. In the observational astronomy, the data acquisition system of turbulence fluctuation measurement based on SD card has practical significance for the design of the telescope dome.
