Abstract: We propose a planar, ultrathin, subwavelength spectral light separator that enables efficient, angularly robust, spatially coregistered decomposition of light into its spectral components. The device consists of a collection of spectrally tuned “meta-atoms” and achieves… read more here.

DOI: 10.1109/tpami.2020.2986764
Abstract: Recovering the shape and reflectance of non-Lambertian surfaces remains a challenging problem in computer vision since the view-dependent appearance invalidates traditional photo-consistency constraint. In this paper, we introduce a novel concentric multi-spectral light field (CMSLF)… read more here.

DOI: 10.1117/1.oe.57.6.061609
Abstract: Abstract. Light fields are four-dimensional parametrizations of rays, extensively used for the representation of the rays emitted from three-dimensional objects. With the increasing availability of spectral imagers, conventional light fields can be augmented by the… read more here.
