DOI: 10.1016/j.optlaseng.2018.01.012
Abstract: Abstract We propose a new scheme to encrypt multiple images simultaneously using two-dimensional binary phase masks. Each of the original greyscale images is first decomposed into two pure phase-only images, which corresponds to the reverse… read more here.

DOI: 10.1021/acssensors.5c02258
Abstract: Supercritical angle fluorescence (SAF) is a near-field collection technique used to create surface-sensitive optical transducers. While SAF biosensors require simpler excitation optics compared with total internal reflection fluorescence (TIRF)-based systems, they rely on complex fluorescence… read more here.
