Determination of the blur size of a radiographic system from density reconstruction

Blurring is a serious problem in hydrotest experiments with high-energy X-ray radiography. We propose a new method that determines the blur size of a radiographic system from density reconstruction. First, we test the method on a simulated image whose blur is known in advance. Then, we apply the method to obtain the blur size of a realistic radiographic system from an experimental image produced by the system. Finally, we verify the obtained blur size via a radiographic experiment on a step object.
