ABSTRACT:
Apparatus for stereoscopically displaying radiographic images of the internal structure of an object and determining the spatial coordinates of a defect image inside the object, comprising: (a) two image display devices; (b) a secondary platform to support one of the two display devices with this platform being provided with horizontal movement means along with displacement sensor means; (c) a primary platform to support both image display devices; the primary platform being provided with movement means to horizontally slide both image display devices concurrently and the movement means being equipped with displacement-measuring means; (d) a sturdy base to support both platforms; (e) two reference lines being transversely aligned across and over the images; and (f) an observing assembly comprising two distinct and separate optical paths with each optical path being composed of properly arranged mirrors and lenses to direct the desired image into the respective observing eye. The optical paths are housed and protected by a casing means which is supported by a supporting member and provided with drive means to move the optical paths transversely; this supporting member being further supported by a sturdy base.
