| Abstract: | After analyzing the design principle and the existed insufficiency of linear array digital X-ray imaging technology, a new digital imaging system which utilizes the latest technological achievements of image intensifier and image sensors has been developed. At the speed of 10m/min, the resolution reaches up to 10. 0 Lp/mm, the IQI sensitivity is between 1.25-1. 60%, image quality meets JB/T 4730-2005 AB requirement. The system can be extensively used in the field of defects inspection towards pressure vessels, boiler, pressure pipe welding as well as casting parts. |
