Intersensor Information Assurance

We propose to design, fabricate, and test a novel x-ray detector for use in industrial CT scanners. This linear detector array combines high spatial resolution and long array length to achieve high-resolution scans on large objects. We propose to supplyan x-ray scanner to the Army Research Laboratory for non-destructive testing that includes this linear array with a commercial flat-panel area detector and a 450 kV x-ray source. The detector concept uses multiple CCD optical sensors optically coupled toscintillator screens in alternate planes that can be extended to any reasonable number of units to form very long detector arrays. Flexible software will synthesize virtual detectors, with variable focus and depth optimized to scanner dimensions andenergy, allowing trade-offs between resolution, contrast, and scan time.
