在Calern天文台使用通用差分图像运动监测器进行Turbulence监测
Turbulence monitoring at Calern observatory with the Generalised Differential Image Motion Monitor
摘要：
广义差分图像运动监测器（GDIMM）是几年前提出的新一代湍流监测仪器。它测量了光学湍流的综合参数，即视宁度、等晕角、闪烁指数、相干时间和波前相干外尺度。GDIMM基于一个全自动小型望远镜（直径28厘米），在其入射光瞳处配备了一个3孔掩模。该仪器安装在Calern天文台（法国），对湍流参数进行连续夜间监测。在这篇文章中，我们提出了在Calern获得的长期和季节性统计数据，并结合GDIMM数据提供了等效湍流高度和有效风速等数量。
英文摘要：
The Generalised Differential Image Motion Monitor (GDIMM) was proposed a few years ago as a new generation instrument for turbulence monitoring. It measures integrated parameters of the optical turbulence, i.e the seeing, isoplanatic angle, scintillation index, coherence time and wavefront coherence outer scale. GDIMM is based on a fully automatic small telescope (28cm diameter), equipped with a 3-holes mask at its entrance pupil. The instrument is installed at the Calern observatory (France) and performs continuous night-time monitoring of turbulence parameters. In this communication we present long-term and seasonnal statistics obtained at Calern, and combine GDIMM data to provide quantities such as the equivalent turbulence altitude and the effective wind speed.
