Did you ever wonder how vampire bats or pit vipers could see in the dark? These animals can see infrared light. They use it to feel their surroundings and seek out their prey. Like humans, they don’t have the ability to see infrared using their eyes. Snakes and bats have other receptors that help them. Humans use infrared cameras and other devices to see this light.
People also use infrared devices to get a feel of the world. For example, companies like Well Health Works use an infrared body temperature scanner. It’s used to check a person’s temperature. Infrared is also used in other ways.
Infrared (IR) radiation is a kind of radiant energy. Also called infrared light, it is invisible to the human eye. But we do feel it as heat. Every creature and object in the universe gives off heat. That means everything has some level of infrared radiation.
Infrared radiation is a type of electromagnetic radiation. This is a series of frequencies created when atoms absorb and release energy. The light we see, radio waves, and x-rays are part of electromagnetic radiation. These are a few of the frequencies making up the electromagnetic spectrum.
Infrared happens at frequencies above that of microwaves. But it’s below that of visible red light. That’s why it’s called “infrared.” Caltech says waves of IR radiation are longer than visible light. Infrared frequencies can range anywhere from 300 gigahertz to 400 terahertz.
What Does Infrared Look Like?
This is one of the questions people often ask about infrared. In theory, you would see a world of temperatures instead of colors. Anything with a temperature can become seen in the infrared part of the color spectrum, even ice.
Hot objects would appear bright in a thermal scanner. The hotter the object is, the brighter it will be. If you have infrared vision and use it on a sunny day, you’ll have a hard time looking at animals, people, and the pavement. You won’t see any specific features though. For example, a human face might become covered with bright light since it’s hot. The fingers and the nose will be cooler, so these are not as bright. This means that a hot object will stand out against a cooler surrounding.
A group of scientists conducted an experiment that would let people “see” infrared. The scientists developed eye proteins that could absorb IR light. This could give people the ability to see the red colors that we can’t see in the normal spectrum. While the world might have a reddish tinge, it won’t be the only color. One of the study’s authors said that an object that looked white would look green if you have IR vision.
What are the Uses of Infrared?
You might not see infrared, but it has a strong presence in your daily life. Infrared technology is now used in a wide range of industries. Here are some of the top uses of infrared:
Night vision is one of the most common uses of infrared radiation. The technology uses IR to have and maintain a clear vision. This is even done in the absence of visible light. Infrared is also used in many ways that allow people to see even in the dark.
Night vision goggles and security cameras are two examples of this technology. Devices that use this technology are often designed to visualize and navigate. But it’s based on heat released in the environment. Take for example a security camera in an empty warehouse. It should not pick up any human heat signatures in the evening.
Remote Checking of Temperature
Infrared is also used to determine temperature differences even without contact. Every object releases some degree of infrared radiation. This manifests as heat. IR technology can compare the emitted radiation. It visualizes and compares temperatures.
Infrared is now used in medicine. Many hospitals and medical personnel use a thermal temperature scanner. It can examine and show which parts of the body have high or low temperatures. This can help hasten a patient’s diagnosis. Infrared is also used to check COVID temperature. Thermal guns and scanner cameras have become more common due to the pandemic.
Infrared technology is an important element in electronics. Infrared light is also used to send signals and data over small spaces. Remote controls exemplify this well. They use IR to send signals to televisions, ACs, and various household electronics. But these signals can’t penetrate walls. This is good as it won’t interfere with the devices in other rooms or a different building.
Thermal imaging uses infrared and thermal energy to get information about objects. It builds on night-vision technology. It can work in the absence of light. Thermal imaging devices can work in all conditions, from smoke to haze.
Thermal imaging has many applications. It can help first responders do their job with more efficiency. It also keeps people who work in this industry safe. For example, firefighters use thermal cameras to see through smoke. They can find trapped people based on their heat signature. These cameras can also show firefighters if there are any danger spots.
