Can Multispectral Imaging been Inspired by Digital Camera?In recent years, multispectral filter array (MSFA) imaging is an emerging technique which inspired by digital cameras featuring color filter array (CFA). However, such method suffers from multispectral demosaicking from the captured raw data, and the sparse...Jul 02, 2020 -
Scientists Prevent Critical Collapse of Higher-order SolitonsSelf-trapped modes suffer critical collapse in two-dimensional cubic systems. To overcome such a collapse, linear periodic potentials or competing nonlinearities between self-focusing cubic and self-defocusing quintic nonlinear terms are often introduced. A... Solitons are stable objects balanced by diffraction or dispersion and nonlinearity. A fundamental challenge in this field is the stabilization of solitons in multidimensional coordinates, since the 2D and 3D solitons in free space are always unstable and un...Mar 06, 2020 -
Scientists Solved Simultaneous Optical Trapping and Imaging in The Axial Plane for Light-matter InteractionOptical trapping has become a powerful tool in numerous fields such as biology, physics, and chemistry. But, in conventional optical trapping systems, trapping and imaging share the same objective lens, confining the region of observation to the focal plane... Optical trapping has become a powerful tool in numerous fields such as biology, physics, chemistry. In light-matter interaction, transfer of optical linear momentum and angular momentum gives rise to optical forces acting on the illuminated object, thus ena...Mar 05, 2020 -
