Thermal imaging works by detecting infrared radiation emitted by all objects above absolute zero. FLIR cameras convert this invisible radiation into a visible image, mapping temperature variations to a color palette that the human eye can interpret.
Italic text functions like a low-temperature reading -- present but secondary, carrying supplementary data without drawing the eye from primary readouts.
Bold text is a thermal hotspot -- an area of concentrated energy that demands immediate attention and analysis.
Inline code elements represent raw sensor data, standing apart from interpreted readings with a digital readout aesthetic.
Every object with a temperature above absolute zero emits infrared energy. The warmer the object, the more radiation it emits. A thermal camera simply makes the invisible visible. FLIR Systems Technical Reference Manual
