Radiometric correction of laser scanning intensity data applied for terrestrial laser scanning

ISPRS Journal of Photogrammetry and Remote Sensing, 2021
Abstract Alongside spatial information, an intensity scalar is also measured by LiDAR (Light Detection And Ranging) sensor systems. It corresponds to the amplitude of the backscattered laser beam after reflection on the scanned surface. This information isn’t directly usable due to dependencies of geometrical parameters occurring during the scanning ...

Feasibility and Limitations of the Advanced Replica Process for Bioactive Glasses

Advanced Engineering Materials, EarlyView.
Periodic 3D‐printed Kelvin‐cell templates enable a controlled advanced replica process for fabricating highly porous glass lattices. Across P45K9, 45S5, and 13–93, material‐dependent differences in coating, burnout, and shrinkage lead to distinct strut morphologies, while comparable final porosities of 83%–88% are retained.

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Comparative analysis of mobile laser scanning and terrestrial laser scanning for the indoor mapping

Building Research & Information, 2023
Efficient three-dimension exploration of a complex indoor environment remains a difficult duration in mapping accuracy requirements for geometric data. Indoor and outdoor mapping, which has been done with classical measuring devices for a long time, has come a long way with the use of laser scanning technology in this field.
