High-Resolution Real-Time Radiography (RTR) System Design.
Abstract
A high-resolution real-time radiography (RTR) system was designed for aerospace component x-ray inspections in the 20 to 300 kV range. Particulate and glass x-ray converters, image intensifiers, and video camera components were performance tested for resolution greater than 10 lp/mm, dynamic range greater tha 1000, contrast sensitivity of 1%, and image size of 12 x12 in. A breadboard RTR system, constructed with optimized components, produced 1024 x 1024 pixels per image with 8 bits per pixel. Computer controlled optical zooming achieved horizontal fields of view from 12.8 to 0.5 in. and corresponding resolutions of 3 to 80 pixels mm. Conceptual high-resolution RTR prototype systems were designed using the test results. Keywords: Real-time radiography; Display screens; X-ray converters.
