X-ray phase-contrast imaging has experienced rapid development over the last
few decades, and in this technology, the phase modulation strategy of
phase-stepping is used most widely to measure the sample's phase signal.
However, because of its discontinuous nature, phase-stepping has the defects of
worse mechanical stability and high exposure dose, which greatly hinder its
wide application in dynamic phase measurement and potential clinical
applications. In this manuscript, we demonstrate preliminary research on the
use of integrating-bucket phase modulation method to retrieve the phase
information in grating-based X-ray phase-contrast imaging. Experimental results
showed that our proposed method can be well employed to extract the
differential phase-contrast image, compared with the current mostly used
phase-stepping strategy, advantage of integrating-bucket phase modulation
technique is that fast measurement and low dose are promising.Comment: 14 pages, 6 figure
