Advances in digital holography, 3-D imaging, and optical information processing: introduction

The Optica Digital Holography and Three-Dimensional Imaging Meeting (DH), held as part of the Imaging Systems and Applications Congress in Seattle in August 2025, served as an important forum for international researchers to present recent work and discuss developments in digital holography, three-dimensional imaging, and optical information processing. The DH meeting provides a venue for research on the science, technology, and applications of digital holography, 3D imaging, and optical information processing methods.
