It’s only in the past few years that the mass production of thermal imaging technologies has reached a point where handheld thermographic cameras (also known as heat cameras, thermal detection or infrared cameras) are now an accessible option for most civil applications and/or hobbyist use.
However, viewing heat energy as an infrared spectrum display isn’t actually a new concept by any means; in fact, the roots of the basic thermography principle were established more than 200 years ago by the German-British astronomer William Herschel:
Although thermal imaging camcorders were still a long way off, Herschel’s findings were quickly used to produce a number of early thermocouple-type modules, which could detect the unseen heat emanating from warm bodies at a considerable distance.
His initial discovery was further developed by many other physicists, engineers, and inventors in subsequent years:
Today, the plummeting cost of cutting-edge technologies like smart sensors, microcircuitry, and WiFi connectivity make thermal imaging digital cameras a popular addition to many professional and household engineering, repair, design, creative, PARANORMAL and hobbyist toolkits.
