Abstract
A deformable trihedral reflector suitable for back reflecting an incident electromagnetic beam includes a trirectangular trihedron with three reflecting faces substantially orthogonal two by two. At least one part of the reflector is made of a piezoelectric material. The piezoelectric material is activated to vary the dihedral angles between the faces of the trihedron in the vicinity of the orthogonality to cause divergence of the reflected beam.
