presentation of a research scientist at VTT who is validating PR3D

https://mfg40.fi/wp-content/uploads/2020/12/VTT-Reijonen-process-monitoring-LUTseminar.pdf

from their comparison to optical tomography and CT it seems that PR3D might be more sensitive to defects than optical tomography, although simply measuring time-over-threshold (ie how long is the part too hot at a given region) is seemingly just as predictive as PR3D.

anyone some ideas?
