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…
A reconfigurable arbitrary retarder array as complex structured matter
Chao He, Binguo Chen, Zipei Song +31
Tuneable retarder arrays, such as spatially patterned liquid crystal devices, have given rise to impressive photonic functionality, fuelling diverse applications ranging from micro…
Intensity adaptive optics
Zimo Zhao, Yifei Ma, Zipei Song +12
Adaptive optics (AO) is a powerful tool employed across various research fields, from aerospace to microscopy. Traditionally, AO has focused on correcting optical phase aberrations…
Topological Protection of Optical Skyrmions through Complex Media
An Aloysius Wang, Zimo Zhao, Yifei Ma +14
Optical Skyrmions have many important properties that make them ideal units for high-density data applications, including the ability to carry digital information through a discret…
