Abstract:

It is well known that luminance from photo-chemical reactions of hydroxyl ions in the upper atmosphere -85 km altitude produces a significant amount of night time radiation in the short wave infrared SWIR band between 0.9 and 1.7 um wavelength. This has been demonstrated as an effective illumination source for night time imaging illumination source for night time imaging applications. The addition, it has been shown that observation of the spatial and temporal variations of the illumination can use to characterize atmosphere tidal wave actions on the sky glow region. These spatio-temporal variations manifest themselves as traveling wave patterns whose period and velocity instabilities. Ground to space observation systems especially those employing adaptive optics are adversely affected by high altitude turbulence and winds. In this paper we propose the use of sky glow observations to predict and characterize image system degradation due to upper atmosphere turbulence.
