dont

There isn't a main verb because it is not a sentence, but a bullet point in a list.

It seems to me that it isn't actually a sentence but rather a rather lengthy noun phrase with a compound head (Le DAS... ou DVS...): “est sensible” has for its subject “la diffusion Rayleigh” within the subordinate introduced by “dont”. But then, why is it “due” instead of “dues” (the referent there being plural, “microdéformations”)? Unless the referent is the sentence “... est sensible aux microdéformations” in which case why isn't it “dû”?

There is a possible parsing in which “dont la diffusion Rayleigh” means something like “including Rayleigh scatter”: « The DAS or DVS, including Rayleigh scatter, is/are sensitive to ... » This would result in a full sentence, but makes zero sense in context. And it still wouldn't account for “due”.
