Thermal Vision Technology

Thermal imaging is based on heat. All objects, both natural and manmade, emit infrared energy as heat.  This energy is actually part of the upper infrared light spectrum. The energy waves can be collected and focused by the right equipment to create a visible image, even when something is not visible to the naked eye.  In complete darkness or in harsh weather, thermal imaging will give the user the ability to see the unseen.

The electromagnetic spectrum includes visible and infrared ray (IR) wavelengths. LWIR waves—used in thermal imaging—are one part of the infrared ray spectrum.
Visible and infrared (IR) wavelengths are part of the continuous electromagnetic spectrum. Within the IR part of the spectrum, there is a long-wave infrared (LWIR) spectrum. There, objects emit energy even when visible light is not present.

Thermal imaging...

  • Can highlight people, animals, and objects
  • Be used to track fugitives or vehicles
  • Works in both daylight and darkness
  • Can see through haze and smoke
  • Isn’t blinded by bright light

Different temperatures are rendered as different levels of brightness (shades of gray) in the visible thermal image. Living things generate their own heat, but even inanimate objects (like rocks) give off the heat they have absorbed from the sun and other sources.
