Abstract
A scanning radiographic system employing a multi-linear array. The system includes a source of electronic radiation, which is focused upon the multi-linear array. The multi-linear array includes radiation sensors each of which is adapted to generate an intensity signal as a function of the amount of radiation sensed thereby. Each sensor has associated therewith a means for holding or storing its respective intensity signals. The intensity signals thus held may be continually up-dated to reflect subsequent intensity signals resulting from additional radiation sensed by the respective sensors. An opaque object to be scanned by the radiographic system passes through the beam of radiation in a controlled fashion. This controlled motion is synchronized and coordinated with the shifting of the up-dated intensity signals so that the speed and course of travel of a particular up-dated intensity signal through the holding means of a given group of said sensors is optically aligned with the speed and course of travel of the radiation passing through a given area of the opaque specimen. In this fashion, there is generated one up-dated intensity signal corresponding to a given area of the opaque specimen. These up-dated intensity signals are then collected and processed by a suitable visual system.
