20.500.12556/RUL-179242 Off-axis reflective phase-only holograms with chiral liquid crystal The growing demand for holography and its wide-ranging applications necessitate advancements to make this technology more accessible and adaptable to modern technological requirements. Nematic liquid crystals (NLCs) enable holographic projection by exploiting the geometric phase of light through carefully designed phase patterns. However, NLC-based holography faces challenges, particularly in terms of projection quality and the presence of zero-order leakage—a bright spot that overlaps the reconstructed image. The efficiency of the reconstructed image is strictly related to the thickness of the NLC layer, which is challenging to control with high precision. In this work, we use chiral liquid crystal (CLC) to fabricate reflective holograms. To address the issue of leakage waves overlapping the reconstructed image, we propose an interference-based fabrication approach. This approach combines the phase pattern of the hologram with a diffraction grating by interfering a plane wave with a tailored wavefront precisely matching the hologram’s phase pattern. As a result, the image is reconstructed away from the zero-order reflection, and the leakage overlapping with the reconstructed image is reduced significantly. liquid crystals holography tekoči kristali holografija true false true Angleški jezik Slovenski jezik Članek v reviji 2026-02-09 12:20:17 2026-02-09 12:20:17 2026-02-10 04:26:32 0000-00-00 00:00:00 2026 0 0 Str. 455-463 iss. 2 Vol. 16 Feb. 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 538.9 2159-3930 10.1364/OME.584778 267715587 ome-16-2-455.pdf ome-16-2-455.pdf 1 9A1B1A27340C65E8D87021F4938DEE18 9a918d45fed9df0ab6edb9c432999425d38d81d56d51b734006682a5fa4fa8ff 557f011d-05a9-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=227559 https://opg.optica.org/ome/fulltext.cfm?uri=ome-16-2-455 0 5bc4cf47-05a9-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=227561 Fakulteta za matematiko in fiziko 0 0 0
