Description
Summary:In order to improve the resolution of acoustical holographic imaging, a new method, i.e. pulse wave holographic imaging has been discussed in the article. Theoretical analysis and computer simulation indicate that the pulse wave holographic imaging has a better resolution than the continuous wave one. In addition, picking up the phase information of reconstructed waves and using deconvolution technology in the processing of imaging, we can further improve the resolution of the imaging.
