Abstract
A radiographic imaging system (10) includes first and second housing segments (10a, 10b) with the second housing segment (11b) having a low-light-sensitivity television camera (13) mounted therein. The first housing segment (11a) has a radioluminescent screen structure (20) fitted within an opening (16). A workpiece (24) is positioned adjacent the radioluminescent screen (20) and between the screen and a source of radiation (25a, 25b). The screen structure includes means for producing a scintillation shadowgraph pattern in response to impingement on the screen of radiation directed through the object. The camera (13) has its optical input section directed toward the radioluminescent screen for receiving the scintillation shadowgraph pattern and has a target means for forming charge patterns corresponding to the scintillation patterns produced on the radioluminescent screen and scanning means for scanning the target means to generate an optical signal corresponding to the charge pattern formed on the target. Both a source of neutron radiation and X-ray is used to produce a shadowgraph pattern on the radioluminescent screen in response to impingement on the screen structure of radiation directed through the object. Signals derived from sequential scans of the target are processed and the signals generated as a result of the exposure of the object to radiation from the neutron radiation source and exposure of the object to radiation from the X-ray source are combined to produced a television display corresponding to the combination of the signals.
