Summary：主动夜视系统：是利用近红外光作光源照明目标，如红外LED、红外灯和近红外激光器等;用低照度摄像机或微光摄像机接收目标反射的红外光，转换成视频信号在监视器荧光屏上同步显示图像，这种夜视仪称为主动红外夜视仪。被动夜视系统：有两种类型，一类是利

Key Words：

主动夜视系统：是利用近红外光作光源照明目标，如红外LED、红外灯和近红外激光器等;用低照度摄像机或微光摄像机接收目标反射的红外光，转换成视频信号在监视器荧光屏上同步显示图像，这种夜视仪称为主动红外夜视仪。

被动夜视系统：有两种类型，一类是利用月光、星光、夜天光等一切很微弱的自然光线，加以放大增强达到可视的目的，这类夜视仪也称为微光夜视仪。另一类是利用远红外敏感的探测器探测目标本身的热辐射，这类夜视仪也称为热像仪。
