A Microkrystite from the Australasian Tektite/Microtektite Strewn Field

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Microkrystites are glassy impact spherules. They contain primary crystallites carrying information on the physical and chemical conditions prevailing during vaporization, melting, and ejection in large impact cratering events. We report on the geochemistry and mineralogy down to nanometer scale of the first microkrystite (ODP1144A,14) from the

Brightness Measurements and Calibration With Airborne and Terrestrial Laser Scanners

IEEE Transactions on Geoscience and Remote Sensing, 2008
Brightness measurement with an airborne or terrestrial laser scanner is a new concept since the intensity information recorded by the laser scanner detectors has, thus far, not been used or implemented in surface brightness studies. This is partly due to the calibration problems and the lack of information on the behavior of laser light in the ...

Angular resolution of terrestrial laser scanners

The Photogrammetric Record, 2006
AbstractKnowledge of a laser scanner's spatial resolution is necessary in order to prevent aliasing and estimate the level of detail that can be resolved from a scanned point cloud. Spatial resolution can be decoupled into range and angular components.
