Whether it is law enforcement or fire fighting, you may have noticed that professionals of these fields often roam around with special viewing instruments. These are none other than thermal imagers or thermographic camera.

Not only that; these devices are often used for domestic purposes like HVAC and maintenance, night vision and security as well as ghost tracking. Thermal imaging is based on the theory that all objects have temperature and emit waves of energy called infrared radiation. These energy waves are translated into a viewable picture with hot objects shown as white and cooler objects as black, with gray shades in between. Recent versions of thermal-imaging cameras offer color images.

However, its root goes almost a century back when it was used in crucial times like wars, calamities and accidents. Here’s how this exceptional device has evolved over time.

Thermal imagers trace their beginnings to the military, when they were developed for the British Navy. Developed by the English Electric ...
... Valve, it was primarily used for shipboard fighting in the fifties and sixties. They were mainly used for visibility in the dark as well as seeing through in a smoke filled battle ground. The first units were considered secured, sensitive military technology, large both in size and cost. Soon, these were used in aircraft during the Vietnam War, as they were reliable and extremely useful.

In the early seventies, the fire department took notice of these superb devices and their nearly endless possibilities. Thus, the first instruments were imported for infrared thermography in this department. However, it was soon discovered that these early models only created a while light during fire and were not as useful as imagined, plus, they were bulky.

Soon, major companies realized the potential in this field and started developing several different types technologies for thermal-imaging devices. Along with this, they even got financial support from the federal government, thus, bringing the necessary change in the thermal-imaging technology by decreasing in price and size. The first thermal imagers for the fire service ranged from $18,000 to $25,000. Demand for thermal imagers during the 1991 Gulf War drove production volumes up and costs came down.

Today, the thermal devicesare found across the globe, in many places. It is less than half of its original size and even cost much lesser. They are often used for many crucial applications, as well as simple ones like predictive maintenance in factories and buildings.
