Let 驴 be a thick dual polar space of rank n 驴 2 admitting a full polarized embedding e in a finite-dimensional projective space 驴, i.e., for every point x of 驴, e maps the set of points of 驴 at non-maximal distance from x into a hyperplane e驴(x) of 驴. Using a result of Kasikova and Shult [11], we are able the show that there exists up to isomorphisms a unique full polarized embedding of 驴 of minimal dimension. We also show that e驴 realizes a full polarized embedding of 驴 into a subspace of the dual of 驴, and that e驴 is isomorphic to the minimal full polarized embedding of 驴. In the final section, we will determine the minimal full polarized embeddings of the finite dual polar spaces DQ(2n,q), DQ 驴(2n+1,q), DH(2n驴1,q 2) and DW(2n驴1,q) (q odd), but the latter only for n驴 5. We shall prove that the minimal full polarized embeddings of DQ(2n,q), DQ 驴(2n+1,q) and DH(2n驴1,q 2) are the `natural' ones, whereas this is not always the case for DW(2n驴1, q).
