I think I understand hyperspectral better than multi- in hyper (plz correct if I’m wrong) the several hundred narrow bandwidth reflective signatures of whatever is being observed is capture and consolidated into a “data cube”, which provides a full “spectral signature” that is specific enough to identify the material.
How does multispectral imaging differ?
Do the relatively broad signatures that are captured still enable a certain level of material differentiation once compiled? Or is it more along the lines of traditional optical imaging, simply capturing R/G/B/IR and overlaying the info to create an “image”?
I realize my wording of this request is atrocious… My deepest apologies and thanks for the help in advance!

Hyperspectral imaging IS Multispectral imaging, but Multispectral imaging is not necessarily Hyperspectral imaging.
Hyperspectral just uses a lot more spectral bands which have a much narrower bandwidth. How many more? There is not a hard definition for where one becomes the other.
It’s like cutting a pie into 4 pieces (multisliced) instead of 100 pieces (hypersliced).
