SGER: Clear Sky Monitor for Ground Based Optical Aeronomy

这项拨款支持一部小说的开发和测试 测定夜空清晰度的光学仪器。一 调制的Ronchi光栅将提供调制的输出， 当观察到广阔的星空时，对天空的清晰度很敏感。 此输出可用于确定天空是否 足够清晰，可以对微弱的夜空进行观测 发射谱线预计这一工具将 特别适用于远程站点或站点的操作 由缺乏判断条件是否 适合观察。发达国家的生殖 仪器预计将是廉价的，其广泛的 应用是可以预见的。

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.
