Ultrafast 3D nanofabrication via digital holography. [PDF]
Nat Commun, 2023 The application of two-photon lithography has been limited by the low writing speed. The authors reported a multi-focus improved lithography platform that employs up to 2000 laser foci to perform parallel fabrication with 90 nm resolution via optimised ...

Dual-comb hyperspectral digital holography [PDF]
Nature Photonics, 2021 Holography1 has always held special appeal as it is able to record and display spatial information in three dimensions2–10. Here we show how to augment the capabilities of digital holography11,12 by using a large number of narrow laser lines at precisely

Automated phase unwrapping in digital holography with deep learning. [PDF]
Biomed Opt Express, 2021 Digital holography can provide quantitative phase images related to the morphology and content of biological samples. After the numerical image reconstruction, the phase values are limited between -π and π; thus, discontinuity may occur due to the modulo

Digital Plasmonic Holography [PDF]
Imaging and Applied Optics 2018 (3D, AO, AIO, COSI, DH, IS, LACSEA, LS&C, MATH, pcAOP), 2018 AbstractWe demonstrate digital plasmonic holography for direct in-plane imaging with propagating surface-plasmon waves. Imaging with surface plasmons suffers from the lack of simple in-plane lenses and mirrors. Lens-less digital holography techniques, however, rely on digitally decoding an interference pattern between a reference wave and an object ...
