20.500.12556/RUL-145268 Controllable shifting, steering, and expanding of light beam based on multi-layer liquid-crystal cells Shaping and steering of light beams is essential in many modern applications, ranging from optical tweezers, camera lenses, vision correction to 3D displays. However, current realisations require increasingly greater tunability and aim for lesser specificity for use in diverse applications. Here, we demonstrate tunable light beam control based on multi-layer liquid-crystal cells and external electric field, capable of extended beam shifting, steering, and expanding, using a combination of theory and full numerical modelling, both for liquid crystal orientations and the transmitted light. Specifically, by exploiting three different function-specific and tunable birefringent nematic layers, we show an effective liquid-crystal beam control device, capable of precise control of outgoing light propagation, with possible application in projectors or automotive headlamps. physics optics liquid crystals materials for optics theory and computation fizika optika tekoči kristali true false true Angleški jezik Slovenski jezik Članek v reviji 2023-04-14 12:53:54 2023-04-14 12:53:55 2023-04-16 03:11:38 0000-00-00 00:00:00 2022 0 0 13 str. art. 352 Vol. 12 Jan. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 535:538.9 2045-2322 10.1038/s41598-021-04164-0 92936195 s41598-021-04164-0.pdf s41598-021-04164-0.pdf 1 44EAC293500544C55386C095636C8081 90968f3c47e75dbf23600b5bf11c50f743f6ad53c6f05bc03b59bc91b38501f1 c523620a-dab2-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=168019 https://www.nature.com/articles/s41598-021-04164-0 0 96fe6a80-dab2-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=168018 Fakulteta za matematiko in fiziko 0 0 0
