Multicolor focal plane arrays provide critical image information.

Richard Gaughan, Contributing Editor

A missile launches from a remote silo, streaks upward through the clouds, then shoots above the atmosphere. There is no chance to stop the re-entry vehicle from hitting its target unless it can first be identified — picked out from the natural Earth background and from the clutter created by decoys it releases. This technically challenging task demands a technologically advanced solution: multicolor focal plane arrays (FPAs). All physical objects emit infrared radiation. Because the intensity of the emitted IR depends only on properties of the object itself, rather than on ambient...Read full article
