1. A scanning mirror comprising:
a mirror block with a reflective surface on one side;
one torsional hinge, said one torsional hinge being integrally formed with said mirror block as a single component;
piezoelectric elements;
flexural structures;
wherein said piezoelectric elements are configured to provide translational motion;
wherein distal ends of said one torsional hinge are attached to said flexural structures, being thereby configured to transform the translational motion of said piezoelectric elements into rotational motion of the distal ends of said one torsional hinge; and
wherein said flexural structures are made of separate flexures attached to opposite surfaces of the distal ends of said one torsional hinge.
