Infrared mode

Infrared mode is when Clone troopers activate a special feature in their helmets which allows them to see in infrared. Infrared is elctromagnetic radiation which is longer than normal light (light that we use) but it's shorter than terahertz and microwaves.

When clones went into infrared mode, they can see various wavelengths of heat. In The Clone Wars episode 1 Ambush, clones used it to figure out where the clones were.
