Phase Retrieval of High Energy Focal Spots with Strong Speckle Noise

Seung-Whan Bahk, Joseph S. Tang, and James R. Fienup

Not Accessible

Your library or personal account may give you access

Abstract

Phase retrieval was successfully performed on the high energy focal spots data affected by strong additive speckle noise by using an error metric based on the statistics of both the speckle and gaussian noise.
