Real Time Digital Tomosynthesis System Dedicated to Industrial Solid Rocket Motor Examination

摘要

Usually, numerical radiographs of large objects such as solid rocket motors, show a poor contrast and a low signal to noise ratio images in the strongly attenuated area. Beside that, in the case of rocket motors, the totality of the object must be examined. The examination time must be as short as possible in order to improve the production rate. To reduce the noise on the images the images, it's necessary to sum static images or to apply imaging methods on moving object. To speed up the processing time of these tasks it's necessary to optimise the algorithms and to execute them on dedicated machines. In this paper we present an original algorithm which implement a tomosynthesis method. The tomosynthesis allows to improve the quality of the radioscopic image and to provide three-dimensional information. We propose herein a software and hardware architecture using this technique in its industrial development phase. This DTS (Digital Tomosynthesis System) allows a real time examination of moving objects.
