In June 2026, the digital holography and 3D imaging community gathered in Taipei, Taiwan, for the Optica Digital Holography and Three-Dimensional Imaging Topical Meeting (DH). The meeting marked not only another successful international exchange, but also an opportunity to reflect on two decades of growth in a field that has steadily moved from optical laboratories into biomedical imaging, display technology, computational microscopy, metrology, sensing and artificial intelligence.
