The History of Thermal Imaging Cameras
Thermal imaging goes all the way back to 1800 when infrared was discovered as a form of radiation beyond red light. While infrared technology has many uses it’s most notable for thermal imaging cameras. A standard camera captures the light we can see with our eyes, but a thermal camera captures “invisible” infrared light, making technology such as night vision goggles possible.
The first thermal camera is almost 100 years old, and it spent much of its early days used in the wars of the 20th century. But today, they’re household items. Anyone can buy a camera with a thermal imaging sensor for just a few hundred dollars and use it as a hobby or recreation.
