What does night vision mean?

When people think or talk about night vision technology, they often think of spy movies. Do they really work? Or are they just another form of movie magic? If you were wondering, technology is very realistic and very effective. The standard night-glass (Night Vision) set allows you to see a person standing 200 meters away on a cloudy moonless night. Isn’t that fascinating?

There are two major types of night vision technology. The first works on the principle of image enhancement. It works by adding the minimum amount of light contained in the darkness and expanding it to where objects can be seen. It collects light from the lower end of the infrared light spectrum invisible to the human eye.

The other method by which night vision technology works is thermal imaging, a process. This process is activated by capturing the upper edge of the infrared light spectrum. This part of the light spectrum is emitted in the form of heat, unlike the light we can detect. The hotter an object, the more light it emits.

Is thermal or Night vision better?

Both night vision systems have several similar components. Each of these systems is made up of an optical element, some kind of signal processing and display monitor. Image enhancement seems to be one of the key technologies in modern night vision systems. Both systems were originally developed for military use. In the United States, there are two classifications for night vision devices. The first is called Millspeck, which refers to military specifications. The other is COMSPEC, which refers to commercial specifications.

This technology has been incorporated into a number of popular products and has been used in a variety of ways. They generally fall into three different categories; Spectators, mirrors and cameras. The scopes are usually mounted by hand or with arms and are monochromatic. These are good for short-term viewing from a fixed location. The user wears glasses and they are binoculars. Since they are worn by the user, they are suitable to be worn for a long time and during movement. Cameras are best suited for surveillance, as they can be stored on a captured recording device or viewed from a remote monitor. This category also includes video images.

Night vision systems have come a long way since the early days of their development. They are now used daily by law enforcement and private investigators. They are used by civilians for wildlife watching, protection, surveillance and personal entertainment. Night vision equipment has become an integral part of modern arsenal. Remember, not everything you see in movies is imaginary.
