Abstract: ABSTRACT The threshold voltage for electro-hydrodynamic convection (EHC) in nematic liquid crystals in the low-frequency convective regime is examined. The addition of dopant species is known to strongly effect the frequency response of this regime.… read more here.

Abstract: In complex imaging settings, optical scattering often prohibits the formation of a clear target image, and instead, only a speckle without the original spatial structure information is obtained. Scattering seriously interferes with the locating of… read more here.

DOI: 10.1364/ol.479873
Abstract: Imaging dynamic strongly scattering scenes remains a significant challenge because it is typically believed that moving objects and dynamic media provide huge barriers. Instead, we use the dynamics of objects and media and put forward… read more here.
