Most people have seen night vision technology in movies but don't know how it work’s. In this article, we are going to tell you who, where and why

1. Why is night vision green？

The main reason is that the image intensification screen inside the device is made of phosphor. This substance is used because of its luminance effect, and when struck by electrons that don’t carry color information, it glows bright green. As the electrons pass through the tube, they flow through a microchannel plate, a disc with millions of microchannels. Striking these microchannels bursts of voltage causes the motion to increase rapidly, forming dense clouds of electrons that intensify the original image. These same electrons then strike a screen coated w / phosphor at the end of the tube. The energy from these electrons creates the greenish image on the screen inside the device. Green phosphor is used because the human eye is most sensitive to the green color pallet and distinguishes more shades of green than any other color.

2. what the color of thermal imaging?

Heat vision cameras have changed the way humans are able to visualize their targets in low light or dark conditions, but they aren't all the same. Besides black thermal and white thermals, there are multiple thermal imaging color palette options to choose from depending on the application and purpose of what you're trying to accomplish.

3.What the difference between night vision and thermal vision on Detection

Thermal imaging detects minute differences in heat when detecting game. Thermal scopes detect radiation and do not require any visible light to produce an image. Thermal imaging devices can be used equally well day and night. Animals generate heat and are warmer than their surroundings making it possible to detect them at great distances using thermal imaging.

Night vision relies on at least some ambient light for detection making detection at great distances more difficult. If shooting at night the moon and stars should provide sufficient light for a night vision scope. In the absence of natural light, IR illuminators are used to generate light. Night Vision at times requires the object to be moving to detect it. In scanning a field, it is possible to skip over an animal that is bedded down with night vision, whereas thermal will identify through brush, tall grass or is not required of movement to recognize the heat source.

4. what the difference between night vision and thermal vision on Recognition and Identification?

2. Once a live animal has been detected a hunter needs to recognize it and identify it prior to making any shots. When using thermal, images are displayed as black and white or various shades of color, and various colors are used to represent temperature. Even though a live object can easily be detected using thermal, recognizing it and identifying it as the desired game at a great distance is more difficult. There is a significant jump in detection range and recognition range when using thermal devices, such as, is that a dog or coyote, is that a calf or pig bedded down.

Night vision on the other hand amplifies light and does not have much variance between detection and recognition, as it is a true optical visualization of the object you are looking at. Night vision is only problematic if the game is camouflaged or is standing still. For these reasons, Night Vision will always be superior in recognition and identification, whereas thermal is superior in detection. Depending on range and distance in which you are hunting, you might receive all the recognition needed out of your thermal device. Therefore, it is best to utilize both of these technologies to their strengths.
