微光观察仪是在微弱光条件下用来观察目标的一种仪器,探测距离是它的一项重要指标。介绍了用实验方法研究天候、背景对微光观察仪探测距离的影响。根据照度的不同,通过测量出夜视仪的作用距离,可准确地表示出人在夜间对目标发现、识别、辩认的程度。将一个目标同其所处的背景或其它目标相区别,得出了具有一定价值的结论。
A glimmer is an instrument used to observe a target under weak light conditions. The detection distance is an important indicator of it. The effect of weather and background on the detection distance of glimmer observer is introduced by experimental method. According to the different illumination, by measuring the distance of the night vision device can accurately indicate the night at the target to find, identify, identify the degree. Differentiating a goal from its background or other goals leads to conclusions of some value.
