| Popis: |
We demonstrate a method for increasing the effective resolution of phase retrieval based on the transport of intensity equation (TIE) named speckle high-resolution synthetic spectrum (speckle-HSS), as the upgraded version of the speckle-TIE approach we proposed before based on the quantitative phase imaging camera with a weak diffuser (QPICWD). Benefit from the phase gradient transfer function (PGTF) and phase transfer function (PTF), the phase blurring caused by the underestimation of phase gradient can be compensated correctly via combining TIE and PTF-based deconvolution. This method broadens the application range, alleviating the artifacts and enhancing the contrast and resolution in more accurate value. The experimental results of live HeLa cells have been presented, showing the effectiveness of the proposed method. |
