Preliminary experimental research of detail sensitivity in fast neutron radiography
Background: Detail sensitivity is an important technical indicator in the fast neutron radiography. Purpose: The spatial resolution and contrast sensitivity have important effects on the fast neutron radiography. Methods: Using the control variable methods
we process the different depth and diameter aperture samples of the polyethylene and Pb. Results: Many fast photographic images are obtained under different conditions. Conclusion: Through digital image processing
the preliminary relationship between the detail sensitivity with spatial resolution and contrast sensitivity were given. When the diameter is small
spatial resolution plays an important role in the detail sensitivity; however
contrast sensitivity plays an important part when the diameter is bigger. At last
a preliminary reference conclusion about detail sensitivity is given. Abstract
