We recently discussed the thermal technology of forward-looking infrared and how roofing contractors can use it to offer inspection services. John Anderson, Product Manager of Security Solutions for FLIR Systems, shared his knowledge here:
Roofing Technologies (RT): Let’s start with the basics. What is thermal imaging and how does it work?
John Anderson (JA): Normal, human vision is limited to a very narrow, “visible” band of the entire electromagnetic spectrum. The infrared spectrum, also called thermal energy, has a longer wavelength than visible light. A thermal imager/camera is essentially a heat sensor that is capable of detecting tiny differences
