Light beam scanning pen, scan module for the device and method of utilization

A device for providing angular displacement of a light beam about a direction selected from the X and Y directions with respect to a Z axis comprising:

• an entrance aperture at a first end of said device for admitting an incoming light beam;
• a first mirror disposed to receive and reflect said incoming light beam;
• a flexible mounting means mounting said first mirror, said mounting means defining said Z axis, and being capable of angular displacement about the X and Y directions;
• distortion means for inducing angular displacement of said mounting means about the X or Y directions;
• a second mirror disposed generally parallel to said first mirror to receive said reflected beam from said first mirror;
• an exit aperture at a second end of said device opposite said first end, said exit aperture being disposed to permit said beam reflected from said second mirror to exit said device as a scanned beam of light proceeding in the same general direction as said incoming beam.

A gyrating optical beam deflector comprising:

• a generally planar flexible member, the plane of said flexible member defining a Z axis perpendicular to said plane and mutually perpendicular X and Y axis in said plane;
• a support coupled to said flexible member at a plurality of spaced apart locations so as to permit flexing of said flexible member intermediate said locations;
• an optical element coupled to said flexible member adjacent said locations;
• and
• means coupled to said flexible member for applying a force thereto so as to flex said flexible member and rotate said optical element about said X axis.
