Sensitivity

Smearing

• Use OFIL’s Corona Cameras to pinpoint corona source by looking at the real occurrences rather than at manipulated pictures through long integration (low frame rate).

• CoroCAM’s long integration technique creates smearing and inability to pinpoint the corona source location.

• Where is the exact corona source?

• How many sources are there?

• What is the emission values of each source?
