Abstract
An object (10) to be radiographically inspected is irradiated in a sequence of different positions with respect to an X-ray beam emitted by a single source (12). A single X-ray detector in an imaging system (13) produces a series of electronic signals corresponding to the sequence of positions at which irradiation of the test object (10) occurs. The series of electronic signals is converted to a pair of series of signals, wherein one series of the pair is delayed with respect to the other series of the pair. The pair of series of signals is displayed as a stereoscopic pair of series of visual images corresponding to different positions at which the test object (10) is irradiated by the X-ray beam. A viewing system (19) causes each eye of an observer to see a different series of visual images, whereby the observer is enabled to preceive a series of stereoscopic X-ray images of the test object (10).
