Near field enhancements from angled surface defects : a comparison of scanning laser source and scanning laser detection techniques [PDF]

open access: yes, 2011
Enhancement of the Rayleigh wave signal amplitude at a surface defect, due to interference of incident, reflected and mode converted waves, has been reported by several authors, and it has been suggested that this could be used as a fingerprint of the ...

The effect of laser scanning strategies on texture, mechanical properties, and site-specific grain orientation in selective laser melted 316L SS

open access: yesMaterials & Design (1980-2015), 2020
Selective laser melting has been used to demonstrate the striking effect of laser scanning strategies on the crystalline texture in 316L SS. The aligned crystal orientation along the tensile direction (Z-axis) could be varied using the scanning strategy.

Development of a Photogrammetric 3D Measurement System for Small Objects Using Raspberry Pi Cameras as Low-Cost Sensors [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The digitisation of cultural objects in museums presents two distinct opportunities. Firstly, it allows for the preservation of the objects and collections themselves. Secondly, it enables their accessibility to the general public as 3D models in virtual

Accurate derivation of stem curve and volume using backpack mobile laser scanning

open access: yesIsprs Journal of Photogrammetry and Remote Sensing, 2020
Forest inventories rely on field plots, the measurement of which is costly and time consuming by manual means. Thus, there is a need to automate plot-level field data collection.
