Innovative Methods for Mobile Frequency Hopping Radio Networks

Not Available Industrial Quality, Inc. proposes to develop a novel three-dimensional radiographic approach for the detection of voids and other discontinuities in thick elastomer components. The proposed technique utilizes a high-resolution flat panel electronic x-ray detector to collect multiple images of the component using different source locations/angles for each image. The images are processed concurrently to permit viewing of the internal structure of the subject along any arbitrarily selected plane. A film-based predecessor to this electronic technique has been used successfully in a wide variety of applications but has been limited by the difficulties associated with exposing, processing, digitizing, registering and analyzing these film images. The full process often required several hours to complete. With the newly available large-area flat panel imagers, the prospect for rapid collection and processing of the images is now available. Many of the difficult steps of processing and registering the films are completely eliminated. Even the exposure of the images is made considerably quicker by the significantly more efficient flat-panel detectors. During the Phase I program a flat-panel detector will be integrated into a special test fixture and used to develop techniques to evaluate Navy-supplied elastomer test components.
