X-RAY BACKSCATTER IMAGING FOR AEROSPACE APPLICATIONS

Abstract

Scatter x‐ray imaging (SXI) is a real time, digital, x‐ray backscatter imaging technique that allows radiographs to be taken from one side of an object. This x‐ray backscatter imaging technique offers many advantages over conventional transmission radiography that include single‐sided access and extremely low radiation fields compared to conventional open source industrial radiography. Examples of some applications include the detection of corrosion, foreign object debris, water intrusion, cracking, impact damage and leak detection in a variety of material such as aluminum, composites, honeycomb structures, and titanium.
