Hello RT community,

is it possible to get other optical data such as Metallic, Roughness with RTI dome?

 

Thanks!

Ale,

Particularly with PTM models, there are a range of visualisation aids, such as specularity, built in to the viewer already.

Re "Metallic" - not sure what you're meaning exactly. RTI cannot perform any analysis of the subject's elemental composition by itself - you may get some clues from the photograph visual wavelength spectra, but you will get more - for bulk composition especially - using, say, XRF (X-Ray Fluorescence) - and hand-held XRF is becoming more common.

Re "Roughness", there is work aplenty on machine vision assessment of 'roughness' as a production quality tool, using direct and scattered light and sometimes fractal analysis, but that is usually associated with prior reference data acquired with a similar part of known RA and RZ.

I think it would be good if you could maybe explain your target / sample type / size / what you're trying to investigate.
