The nighttime airglow, or nightglow, correspond to the intensity of a candle at 100m distance. 夜间辉光或夜辉相当于在100米距离的一支烛光的强度。
The main drawback for relying on nightglow is that it does not penetrate ceilings or walls. 夜辉的主要缺点则是无法透视屋顶或是墙壁。
The company also plans to aim for military applications, to perhaps field-test nightglow goggles by the end of 2008. 他们也把目标放在军事应用上，今年底夜辉视镜或许便会进行实地测验。
Conventional digital imagers typically rely on silicon, and they do not detect nightglow. 基本上以矽制成的传统数位成像器材，无法侦测到夜辉（nightglow）。
The company also plans to aim for military applications, to perhaps field-test nightglow goggles by the end of 2008.The U. 他们也把目标放在军事应用上，今年底夜辉视镜或许便会进行实地测验。
Image intensification amplifies what visible light is available, meaning that systems using that approach would suffer under dark skies, whereas nightglow vision would not. 影像强化会增强接收到的可见光，亦即使用这种技术的系统无法在黑暗的夜空中获得影像，而夜辉视像则可以。
