History of Infrared

Since the main source of infrared radiation emitted by hot and thermal radiation, all the objects and all that have a temperature, has a certain temperature emit a level that can be detected by infrared wavelength detection technology. Even very cold temperatures, such as dry ice, the radiation in the infrared. A good example would be the thermal radiation from a hot plate. Although the hot plate does not emit light, they emit infrared radiation in the form of heat. Generally, the heat of an object, the more infrared emitting it as heat. So where we see infrared?

Planet Earth

A little piece of history. When scientists and philosophers believe that the world is flat, no one has the opportunity to question them. You see on the horizon, and it just seemed like the world has its advantages and you fall right here on Earth. During the age of the Crusaders, they make it their mission to prove these theories wrong and to discover new lands.

In 1966, Neil Armstrong on the moon. He turned to look at how our world is round. He noted that not all people have the buildings that came out like a topographical map. Earth appears as a blue ball, with patches of white clouds and green earth. Then in 1986, scientists using the image of the Earth taken by satellites, and change the image using infrared technology. He uses a system of 256 colors to give the Earth a more dramatic look.

The picture was amazing. Not only the images look more detailed than ever, having the science to further study the relationship patterns of wind and cloud structure near the water or nearby mainland. Clouds can be seen as white photography, but with infrared technology, the depth and movement of clouds becomes available. Hurricanes and tornadoes better predicted using infrared imaging to determine the pressure above and below. Weather conditions have become more accessible to a meteorologist, and the best part of all this, we can take great photos of everyday objects using infrared cameras.


Humans have a body temperature that remains constant for some, unless someone has a fever or a cold. Generally, we emit a strong wavelength normal body temperature. An infrared camera can show the signature of the heat emitted from the various parts of our body. What makes this possible is an infrared sensor in the device. However, most cameras have an infrared filter that prevents wave detection. Without this filter, many cameras will not be able to take pictures without detecting thermal signatures that are different from each object. You can also customize the use of false color, which is an amazing feature that allows you to view images in a unique way. So, instead of seeing clearly "visible" energy light images with exceptional color, such as green grass and blue skies, which will display a picture with a dark and light red, yellow, blue ground, orange and black, to name a few.
