摘　　要：望远镜圆顶附近的温度变化等对望远镜成像质量的影响称为圆顶视宁度。为了检测圆顶温度的变化,本文设计基于SD卡的微温脉动仪数据采集系统,用来监测望远镜圆顶周围环境微温变化,实验结果表明,该采集系统可以实现多通道大量采集数据的功能。在实测中,对望远镜圆顶的设计具有实际意义。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.
