Holographic characterization embedded in closed-loop functionalization process of polymeric membranes

Le résumé fourni par la source

Spatiotemporal scanning digital holography (STDH) is a holographic method proposed for characterizing large-size or moving objects. Here, we show that holographic spatiotemporal characterization could be embedded into closed-loop functionalization process of polymeric membranes; its infinite field of view (FoV) characterization capability allows fullfield imaging of polymeric membranes. By implementing phase characterization on polymeric membranes during their multi-step fabrication processes, effective quality control can be performed: a full-field inspection of the homogeneity of the PLGA membrane was performed and a precise control of the fabrication area was achieved during the early stages of film forming; a complete characterization pipeline was established to measure the size and volume of the clusters of nanoparticles.
