Occasionally, these products are very expensive during the launch phase, but once early users have a chance to buy and the product can be put into mass production, the price drops rapidly and some can even become everyday items. The phone is a clear example. The phones were bulky and expensive at launch, but then quickly grew into palm-size products for everyday use by millions.
Past and present of thermal imaging
We now see a very large number of common technology, initially used mostly in the military field. Radar and jet engines were originally developed by the military and used for military applications. The Global Positioning System, commonly known as GPS, was developed by the U.S. Department of Defense to control missiles in the early 1970s. GPS is also a very expensive system when it is first integrated into a car for civilian use. Today, almost every new car is equipped with a GPS system.
However, the first ancestor of all military inventions was the concept that Pentagon officials called the "Intergalactic Network." This crazy concept eventually became the Internet. There is no doubt that it is this military invention that has largely changed our world.
Today, there is another technology that has its roots in military applications and has played a significant role in many useful civilian areas. This technology will not only change our lives, but also save lives. This technique is called: thermal imaging.
Unlike a normal camera that relies on light to produce an image, a thermal imager, sometimes called an infrared camera, recognizes tiny temperature differences and transforms them into crisp, thermal images that make the details a reality. Unlike other technologies, such as light amplification, which requires at least a small amount of light for imaging, thermography can observe things in a completely dark environment without any light.
The first military camera was developed by a company called AGA in 1958, the company that is today's FLIRSystems. With the ability to produce crisp images in completely dark surroundings, thermal imaging can see the target hostile forces in the darkest night. The camera can be used for light fog and snowy weather and can also penetrate the smoke to make it more practical for the military as the warrior can see the other end across the smoky battlefield.
The first commercial thermal imager was introduced in 1965 to inspect transmission lines. It was not until 1973 that the first "portable" battery-powered thermal imaging camera appeared.
Although called "portable," the system is still heavy. The technology used at the time required the imager to be filled with liquid nitrogen to cool the integrated infrared detector in the system. This approach continued until FLIRSystems introduced the first system to eliminate liquid nitrogen-cooled detectors in 1985, replacing a so-called cooler.
Until 1997, thermal imaging cameras equipped with uncooled detectors, known as microcalorimetric detectors, entered the market. One of the main advantages of a microcalorimeter is that it has no moving parts and is therefore less prone to failure. In addition, its production price is cheaper, so the thermal imager manufacturer can lower the price of its products.
From military to industrial applications
Although thermal imaging cameras are commonly used in military applications, they did not begin to be used in commercial and industrial applications until the introduction of trace thermal detectors.
The first industrial customer to discover the benefits of thermal imaging is the large manufacturing company. Not only can thermal imaging based on temperature difference imaging, but also to measure these temperature differences explicitly. Thanks to the complex algorithms used by thermal imaging cameras, absolute temperature values ​​can be calculated.
The industry quickly discovered that thermal imaging can provide valuable information about electrical equipment. Fuses, connectors, cables, and high-voltage equipment, such as transformers , power lines, etc., are all easily accessible for non-contact inspection with thermal imaging cameras. The advantage is that thermal imaging can help maintain the administrator to detect anomalies in advance to avoid problems. In this way, you can avoid costly failures and save time and money.
But in the same company, R & D has also had a great deal of enthusiasm for thermal imaging.
Its biggest advantage is the use of infrared thermography early in the product design cycle. In the development phase, put into mass production, the electrical equipment should be fully tested. Consumers look forward to getting the perfect product at an affordable price. With infrared technology, companies can shorten the development phase and quickly get the return on their development investment.
More and more industrial companies are beginning to use thermal imaging technology, enabling businesses to take the first step toward implementing so-called mass production. Even so, the camera is still expensive and costs 20,000 euros or more. For customers, thermal imaging is still a very novel technology. The thermal images customers see are limited to Hollywood films such as Predators I and II.
From industrial applications to civilian mass production
So what happened? How does thermal imaging fit into the customer's everyday life? What are their advantages?
After that, the same "BMW Night Vision" component has also become an optional accessory for the BMW 5 Series and 6 Series. The massive demand for this security option has enabled FLIRSystems, the world leader in thermal imaging products, to increase production dramatically. Today, FLIRSystems has produced thousands of thermal imaging cameras solely to broaden the driving perspective. One of the consequences of this increase in output is the significant reduction in the price of thermal imaging cameras.
However, mass production is not only driven by consumer staples, but military applications also play a role, and the UAV is one of the drivers. UAVs are becoming more commonplace in the military and civil sectors, especially small aircraft designed for low-altitude flights. These manually activated radio-controlled aircraft can carry cameras connected downstream to the ground station and are absolutely suitable for detecting operations or tracking the movement of troops on the battlefield.
A few years ago mass production of thermal imaging cameras took an important step forward. At that time, BMW, one of the world's leading automakers, decided to use a thermal imaging camera in its Deluxe Series 7 to broaden its horizons. At the same time, improving passenger and driver safety is also one of BMW's top priorities. Due to the large number of traffic accidents caused by night driving, BMW wanted to find a solution to reduce the accident rate.
The military first discovered that the camera could make the plane fly in a completely dark environment and could traverse the smoke and clouds to detect targets. Very quickly, civil applications have also kept pace. Today, such aircraft can also be used to detect targets such as forest fires. Temperature is higher than week
