Spectral light fields for improved three-dimensional profilometry Academic Article uri icon

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 additional spectral information, yielding a five-dimensional ray parametrization referred to as a spectral light field. We demonstrate that utilization of the spectral channel information can improve the profilometric performance of light-field cameras. © 2018 Society of Photo-Optical Instrumentation Engineers (SPIE).
