SGER: Clear Sky Monitor for Ground Based Optical Aeronomy

这笔拨款支持一种新型光学仪器的开发和测试，以确定夜空的清晰度。一个被调制的Ronchi光栅将提供一个对天空清晰度敏感的调制输出，当一个广阔的星场被观测时。这个输出可以用来确定天空是否足够清晰，以便对微弱的夜空发射线进行观测。预期这一仪器将特别适用于从偏远地点进行的作业，或由在判断条件是否适合观察方面缺乏经验的人员操作的作业。研制的仪器的再生产预计价格低廉，可预见其广泛应用。

This grant supports the development and testing of a novel optical instrument for determining night sky clarity. A modulated Ronchi grating will provide a modulated output that is sensitive to sky clarity when a wide field of stars is observed. This output can be used to determine whether the sky is sufficiently clear to conduct observations of faint night sky emission lines. It is expected that this instrument will be especially useful for operations from remote sites, or from sites operated by personnel inexperienced in judging whether conditions are suitable for observations. Reproduction of the developed instrument is expected to be inexpensive, and its widespread application is foreseen.
