Stereoscopy (3-D Imaging)
To further assist the inspector in locating and measuring areas of
interest with the main object, the reverse geometry system can display real time images in
stereoscopic "3-D". This procedure requires two detectors. The amount of
separation of the detectors determines the strength of the 3-D effect. The radiographer
wears polarized glasses to view a display monitor with a polarized shutter. Quantifiable
measurements of length, area, and depth can be made in three dimensions.
