1. An optical scanner comprising:
a cantilevered beam assembly, comprising:
a stationary portion;
a pivoting portion comprising a cantilevered beam dimensioned to resonate in a bend mode in a plane at a first frequency;
at least one torsional flexure coupling the pivoting portion to the stationary portion, the at least one torsional flexure being configured to allow the pivoting portion to rotate about an axis defined by the at least one torsional flexure; and
a transducer for maneuvering the cantilevered beam in a scan pattern.
