Distally Actuated Scanning Mirror

A laser beam scan structure comprising:

• a first shear-mode piezoelectric element;
• a first flexure element, said first flexure element having a first end secured to said first shear-mode piezoelectric element, said first flexure element configured to extend away from said first shear-mode piezoelectric element to a distal end;
• a second shear-mode piezoelectric element;
• a second flexure element, said second flexure element having a first end secured to said second shear-mode piezoelectric element, said second flexure element configured to extend away from said second shear-mode piezoelectric element to a distal end;
• an elongated hinge, said elongated hinge configured to extend from said distal end of said first flexure element to said distal end of said second flexure element;
• a mirror, wherein said mirror comprises a reflective surface;
• a first mass, said first mass being fixedly secured to said distal end of said first flexure element;
• a second mass, said second mass being fixedly secured to said distal end of said second flexure element;
• wherein said first shear-mode piezoelectric element is configured to alternately expand and contract to drive said first flexure element to oscillate;
• and
• wherein said second shear-mode piezoelectric element is configured to alternately expand and contract to drive said second flexure element to oscillate.
