Field-Programmable Topological Torons in Chiral Nematic Liquid Crystals
Adithya Pradeep, Urban Mur, Ji Qin +7
Torons are three-dimensional double-twist solitons in chiral nematic liquid crystals that form localised director configurations protected by topology and bounded by closed defect…

Tunable Dynamic Speckle Generation for Random Illumination Microscopy
Lilian Magermans, Assia Benachir, Nathan P. Spiller +7
Speckled illumination enhances widefield fluorescence microscopy by enabling optical sectioning and super resolution. In random illumination microscopy, sequences of speckled illum…

Speckle suppression in digital in-line holographic microscopy through liquid crystal dynamic scattering
Emilia Wdowiak, Nathan Spiller, Tianxin Wang +7
We demonstrate speckle noise reduction in an in-line holographic imaging system using a Zwitterion-doped liquid crystal dynamic scatterer (LCDS) cell diffuser. Integrated into a mi…
