Investigating the variation of particle distribution and surface texture of top surfaces based on build position in laser powder bed fusion (2024)
Journal Article

Quality analysis of additively manufactured (AM) surfaces is complex, yet critical for determining the functionality of parts and technology improvement. To accurately assess the quality of AM parts, it is necessary to consider the industrial applica...

Extracting focus variation data from coherence scanning interferometric measurements (2024)
Journal Article

Coherence scanning interferometry (CSI), based on the principle of interference, can achieve sub-nanometer precision for height measurements. On the other hand, focus variation microscopy (FVM), combining the small depth of field of the objective, is...

Comparison of Fourier optics-based methods for modeling coherence scanning interferometry (2024)
Journal Article

Coherence scanning interferometry (CSI) is a widely used optical method for surface topography measurement of industrial and biomedical surfaces. The operation of CSI can be modeled using approximate physics-based approaches with minimal computationa...

Enhancing single camera calibration results using artificial bee colony optimisation within a virtual environment (2024)
Conference Proceeding

Close range photogrammetry is among the top candidates for non-contact metrology in high precision applications. It is frequently used within industrial environments for high precision measurement, automation, and control tasks. When using off-the-sh...

Assessing the spatial distribution of positional error associated to dense point cloud measurements using regional Gaussian random fields (2024)
Journal Article

Being able to assess the amount of uncertainty locally associated to dense point clouds generated by measurement can help investigate the relations between the metrological performance of a chosen measuring technology, and the local geometric and sur...
