Here, we demonstrate how a recent extension of piezoresponse force microscopy (PFM), known as interferometric vector PFM, can be utilized for simultaneously mapping the local crystallographic orientation and the domain structure of distributed grains in uniaxial ferroelectric polycrystals, without requiring complementary characterization techniques, such as electron backscattered diffraction (EBSD). By shifting the laser beam position on the cantilever, direction\u2010dependent piezoresponse signals are acquired analogous to classical vector PFM, but without the need to rotate the sample. Using polycrystalline  as a model system, we demonstrate that the reconstructed piezoresponse vectors correlate one\u2010to\u2010one with the crystallographic orientations of the micrometer\u2010sized grains, carrying grain\u2010orientation and domain\u2010related information. We establish a versatile approach for rapid, multimodal characterization of polycrystalline uniaxial ferroelectrics, enabling automated, high\u2010throughput reconstruction of polarization and grain orientations with nanoscale\u00a0precision.<\/jats:p>","DOI":"10.1002\/smll.75372","type":"journal-article","created":{"date-parts":[[2026,9,3]],"date-time":"2026-09-03T10:29:57Z","timestamp":1788431397000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Interferometric Vector Piezoresponse Force Microscopy for Simultaneous Ferroelectric Domain and Crystallographic Orientation Mapping in Uniaxial Ferroelectric Polycrystals"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-3642-2779","authenticated-orcid":false,"given":"R.","family":"Dragland","sequence":"first","affiliation":[{"name":"Department of Materials Science and Technology Norwegian University of Science and Technology (NTNU) Trondheim Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7389-1295","authenticated-orcid":false,"given":"J.","family":"Schulthei\u00df","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Technology Norwegian University of Science and Technology (NTNU) Trondheim Norway"},{"name":"Centre for Materials Science and Nanotechnology (SMN) University of Oslo  Oslo Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-6221-2737","authenticated-orcid":false,"given":"I.
