Blazing Its Own Path
By Sherry Robinson
Infrared technology isn't exactly a household word but it should be. You use it to play your CDs. And some new camcorders can now shoot at night using a sensor that works in infrared.

The military has used infrared devices since World War II to see in the dark. For both surveillance and countermeasures infrared is still a hot research area to the nation's defense agencies, and the same technology lends itself to commercial applications. more
