Note: Many topics at this site are reduced versions of the text in "The Encyclopedia of Networking and Telecommunications." Search results will not be as extensive as a search of the book's CD-ROM.

Infrared is the region in the electromagnetic spectrum that falls between radio waves and visible light. Infrared can't be seen, but it can be felt as heat given a strong energy source. A camera equipped with infrared-sensitive film can take pictures of "warm" objects in low-light environments. Most people are familiar with infrared as implemented in remote control devices.
