红外夜视系统的鉴别率

Resolution of IR Night Vision System

主动式红外夜视系统的鉴别率是评价其性能优劣的一个重要参数，它不仅对夜视系统的成像质量有影响，而且对夜视系统探测目标距离的能力也有影响。本文比较系统地叙述了影响直视红外夜视系统鉴别率的内部因素与外部因素，从中可以寻找出改善直视红外夜视系统鉴别率的方法。

Resolution is an essential parameter in evaluating IR night vision systerms,which determines the inage quality and detecting distance. All the sources which have effects on the resolution are discussed. This may be helpful in finding some ways to improve it.
