Abstract

We present the multimodal characterization of thin polymeric membrane by digital holography-based methods. Herein, two microscope techniques had been chosen to reveal the morphology of membranes, which are conventional off-axis Digital Holography (DH) and Space-Time Digital Holography (STDH). The complementary features of the different methods allow for a bottom-up analysis of the related membranes. Meanwhile, the dynamic forming process of polymeric membrane at the air-water interface is revealed in real-time by CDH. By comparing the imaging results of different methods, the application range of different imaging methods is analyzed in detail.
