Intensity Data Correction for the Distance Effect in Terrestrial Laser Scanners

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2016
Terrestrial laser scanning systems deliver geographic coordinates and backscattered intensity values, which are acknowledged as significant observations that can be used in a wide range of applications. However, the direct use of these original intensity data is not recommended because they are influenced by multiple variables, especially distance and ...

Fast Programming of in‐Plane Hyperbolic Phonon Polariton Optics through Van der Waals Crystals Using the Phase‐Change Material In3SbTe2

Advanced Science, EarlyView.
Launching structures for in‐plane hyperbolic polaritons in α‐MoO3 are optically programmed through already deposited flakes into the phase‐change material In3SbTe2. Precise alignment with the flake's crystal axes, focusing of polaritons by an optically programmed disk, and a first experimental realization toward a nanocavity for in‐plane hyperbolic ...
