[photogrammetry]
A technically complex way to display the terrain stereoscopically using a special computer monitor that alternates two images at least 30 times a second. The first image is displayed with horizontally polarized light, the second with vertically polarized light. Stereoscopic analysts wear special goggles with polarizing filters that allow the right eye to see only the horizontally polarized image and the left eye the vertically polarized image, so that the terrain is seen stereoscopically in the mind. Also called stereoscopic projection.
