If you have paid attention to night vision cameras, you have seen that they are generally green in color. While there is a very simple reason for this, many of us still think about why green tones are used.
night vision camerasIt plays an important role in the field of security and surveillance by offering the ability to obtain clear and detailed images even in low light conditions.
On the screens of these cameras predominance of green tonesdepends on technology’s relationship with human anatomy!
The human eye perceives green color better than other colors and is more sensitive to green color.
In this situation Images taken at night are clearer and makes it look detailed. Technologies used in night vision systems create an image by concentrating existing low light or infrared light. These images are displayed through phosphor screens, which display images in green tones.
However, the reason why green is preferred is of course various. one of them reducing eye fatigue. Green color is one of the most comfortable colors for the eyes and keeps eye fatigue to a minimum during long-term use.
Of course, the human eye can distinguish tone differences in green better than other colors.
This means that night vision devices more detailed and clear images helps provide. In addition, green tones provide the best contrast in low light conditions. Thus, we can see clearer images on the screen.
Let’s get down to business technical details…
night vision devices, in low light conditions It takes the available light and concentrates it. These devices also detect infrared light, which is usually invisible to the eye, and convert this light into the visible spectrum. However, this conversion is carried out through phosphor screens, and phosphor screens generally produce a green color.
In some night vision devices, technologies are used to shift the blue part of the light to the green spectrum and the red part to infrared.
Such techniques are also clearer and contrasty images enables it to be obtained. However, this shifting process is not directly the main reason why the image appears green.
The main reason is Phosphor screens produce green color and this is nothing more than the better perception of color by the human eye.
