How can the military track down civilians in pitch black? A gadget called Night Vision Goggles. These were first invented by Kalman Tihanyi, a physicist who developed the idea for the Hungarian military in the 1930’s.They were originally thought of so tank drivers could see heir surroundings in the night so they could continue fighting. Night Vision Goggles help you see in the dark by using one of three ways. The first technology that is used in Night Vision goggles is called image enhancement. This kind of technology takes all possible light and makes it visible. As you may know, not all light is visible to the raw eye. In fact, the only wave of light humans can actually see is visible light. In order to see all other light, we need assistance. A great source of assistance to humans is called Night vision. Night vision helps us see all light, which includes many different types of light.Visible light excludes gamma rays, radio waves, micro-waves, x-ray waves, human eye transfers it through layers of the googles to make it visible to the human eye. The way this is possible is by transferring non-visible light and pushing it through multiple lenses of night vision goggle and applying a green glow to the now visible light. The reason there is a green glow is because humans are most sensitive to green colors. Some examples of this kind of night vision are some used in action movies and the military. This type of night vision technology is the most common out of all 3 different types. Another type of Night vision is named thermal imaging. This applies a blue/grey tint to the final image collecting a measure of temperatures called a thermogram of the surroundings and turning it into visible light. It also collects all light in the upper portion of the electromagnetic spectrum. This light includes gamma rays, infrared waves, and x-rays. Thermal imaging captures and reads infrared rays from plants and humans and about everything in your surroundings. This technology can sense things far away or close. Helicopters use this way of night vision a lot. This type of technology is commonly used in helicopter radar and wildlife surveillance. The third type of technology of is called Active Illumination. This takes both technologies and combines them into one. Active illumination lights up in surroundings in order to make a clear image. This is possible because it uses infrared scanners to locate near objects. Then, it uses all other light that is invisible to our eyes to clarify an image. This is by far, the most rare edition of night vision available to us. There are many ways to see things in an unexpected environment. Night Vision goggles are the most common answer. Night vision is used for many reasons. Many people can effectively use the privilege of night vision. Even regular people can use i for whatever they want! It’s amazing how far the technology of Night vision goggles have come. One day they are only used in goggles, and the next it is used for numerous other purposes. Some of the people who use Night Vision are hunters who use it to locate animals, the military to track down armies of other countries, environmentalists that use it for wildlife surveillance. Also, smartphones use it for the purpose of taking pictures in low lit situations. TSA uses night vision and x-ray vision to look into luggage and carry on items to prevent planes from getting hijacked and ensuring safety of many people. Some form f night vision technology is used in navigation to determine where you are, what your surroundings include, and where to go next to arrive at your destination. Police use the technology for different purposes as well. They use it to track down criminals in helicopters and use it in their navigation to find out where the scene of a crime is. Self- driving cars use Night Vision technology to sense surroundings in the dark so they don’t crash into other cars. Backup cameras used on mobile vehicles use night vision to help the driver and assure they aren’t going to back u too far and hit anything. As you can, see night vision is technology that you can get if you are a government operation or if you are a regular civilian looking to have some fun or use it for something like hunting. There are also three different types of technology used in Night Vision. These types are called Image Enhancement (Image Intensification), Thermal imaging, and Active Illumination.
