• Detects Infrared Radiation and sends it to the display.

• Primary source of IR

  • Thermal radiation (heat)

• Anything above Absolute zero

  • (-273 °C -497°F)

  • Emits radiation

• 2/3 of Earth's heat

  • Received through IR

• We can feel the heat but can't see it

• Measures the intensity of the IR thermal spectrum

• Eyes see “VISIBLE” electromagnetic spectrum

  • ROYGBIV - colors of a rainbow

• Radio waves are always in the air

  • We can't hear them.

  • Radios take those waves

  • Convert them into an audible sound 

• Thermal Imaging Cameras do the same with infrared radiation
