夜视眼镜晚上能看清东西吗 - Can night vision glasses see things at night

文章导读

对于有车一族来说,日常开车必备的用品一样都不能少,包括防止大灯直射的眼镜。白天还好,日光充足视线不会受到影响,可以随便买一副太阳镜戴了,而到了晚上,选择何种眼镜就需要认真考虑了。有很多车友认为夜视眼镜是非常不错的选择,那么夜视眼镜晚上能看清东西吗?

夜视镜是基于夜视技术同时借助光电成像器所做的辅助观察工具。夜视镜有三种,一种是微光夜视镜,一种是红外夜视镜,还有汽车驾驶夜视镜。

夜视技术是借助于光电成象器件实现夜间观察的一种光电技术。夜视技术包括微光夜视和红外夜视两方面。微光夜视技术又称像增强技术,是通过带像增强管的夜视镜,对夜天光照亮的微弱目标像进行增强,以供观察的光电成像技术。微光夜视仪,是目前国外生产量和装备

量最大和用途最广的夜视器材,可分为直接观察(如夜视观察仪、武器瞄准具、夜间驾驶仪、夜视眼镜)和间接观察(如微光电视)两种。红外夜视技术分为主动红外夜视技术和被动红外夜视技术。主动红外夜视技术是通过主动照射并利用目标反射红外源的红外光来实施观察的夜视技术,对应装备为主动红外夜视仪。被动红外夜视技术是借助于目标自身发射的红外辐射来实现观察的红外技术,它根据目标与背景或目标各部分之间的温差或热辐射差来发现目标。其装备为热像仪。热成像仪具有不同于其他夜视仪的独特优点,如可在雾、雨、雪的天气下工作,作用距离远,能识别伪装和抗干扰等,已成国外夜视装备的发展重点,并将在一定程度上取代微光夜视仪。

微光夜视镜是把微弱的光放大了,使之在视线中呈现清晰的画面,所以,在完全没有光的情况下,微光夜视镜是看不到东西的。

红外夜视镜又分两种,一种是主动式的,一种是被动式的,主动式的就是夜视镜发出一束红外线,照到物体上再反射回来,相当于手电筒;被动式的则是把物体自身发出的红外线放大转化为可见光。因此,如果没有红外源的话(大多数能产生热量的东西都能成为红外源,如生物、车辆、火焰等),被动红外夜视镜也是看不到东西的。

主动红外夜视镜在任何情况下都能看到东西。不同的夜视镜有不同的适用场合,微光夜视镜适合野外有星光或月光的时候使用。

因为夜视镜只显示单色,而它的显示屏是绿色的(你可以注意到很多仪表的显示屏都是绿色的),所以你看到的是绿色的。

For a car family, there are no fewer necessities for daily driving, including glasses that prevent direct headlights. The daytime is good, the sunlight is not affected, you can buy a pair of sunglasses, and in the evening, what kind of glasses should be carefully considered. Many car lovers think night vision glasses are very good choices. So can night vision glasses see things at night?

Night vision mirror is an auxiliary observation tool based on night vision technology and photoelectric imager. There are three kinds of night vision goggles, one is the low light night vision mirror, the other is the infrared night vision mirror, and the car driving night vision mirror.

Night vision technology is an optoelectronic technology that realizes the night observation by means of photoelectric imaging devices. Night vision technology includes two aspects: low light level night vision and infrared night vision. The low light night vision technology, also called image enhancement, is a photoelectric imaging technique for observing weak targets illuminated by night sky light with a night view mirror with an enhanced tube. The low light level night vision instrument is the foreign production and equipment at present.

The largest and most widely used night vision equipment can be divided into two kinds of direct observation (such as night vision observation instrument, weapon sight device, night driver, night vision glasses) and indirect observation (such as micro light TV). Infrared night vision technology is divided into active infrared night vision technology and passive infrared night vision technology. The active infrared night vision technology is an active infrared night vision device, which is implemented by the active irradiation and using the infrared light from the target to reflect the infrared light. Passive infrared night vision technology is an infrared technology which is observed by the infrared radiation emitted by the target itself. It finds the target according to the temperature difference or the thermal radiation difference between the target and the background or the target parts. Its equipment is a thermal imager. The thermal imager, which is different from other night vision devices, can work in fog, rain, snow, distance and can identify camouflage and anti-interference. It has become the focus of the development of foreign night vision equipment, and will replace the light night vision instrument to a certain extent.

The light night view mirror magnifies the faint light to make it clear in the line of sight, so in the complete absence of light, the light night view mirror is not visible.

The infrared night vision mirror is divided into two kinds, one is active, the other is passive, the active one is that the night vision mirror sends out a bunch of infrared ray, which is reflected back to the object, equivalent to the flashlight; the passive type is the infrared amplification of the object itself and the visible light. Therefore, if there is no infrared source (most of the heat can be made to be an infrared source, such as biology, vehicle, flame, etc.), the passive infrared night vision mirror can not see anything.

The active infrared night vision mirror can see anything in any case. Different night vision mirrors are suitable for different occasions. Low light level night vision glasses are suitable for starlight or moonlight in the wild.

Because the night vision mirror only displays the monochrome, and its display screen is green (you can notice that a lot of the display screens are green), so you see green.
