Utilizing Point-Spread Functions of X-ray Sources to Increase Image Resolution of Shaped Charge Jet X-radiographs

Abstract

A method was developed to deblur radiographs using a point-spread function acquired from the X-ray source to create sharper radiographic images with greater spatial resolution. The deblurring process includes compensation for image artifacts resulting from the X-ray generation across a finite area instead of from an ideal spot. A demonstration of the technique was performed for copper tubes and rods from less than 1 mm to 6 mm, representative of shaped-charge-jet dimensions. Radiographs resulting from the application of the point-spread function deconvolution technique and the subsequent analysis of the copper tubes and a copper shaped charge jet are presented.
