Patent ID: 8081362

Claim:
A galvanometer scanner, comprising: a mechanical support unit engaged with a far end of an optical element, wherein a near end of the optical element is connected to an output shaft of an electric rotary motor, wherein the mechanical support unit maintains an alignment of an axis of rotation of the optical element and an axis of rotation of the electric rotary motor, wherein a tensional mode is J mt {umlaut over (θ)} mt +Kθ mt =Kθ o , J o {umlaut over (θ)} o +Kθ o =Kθ mt where, J et , is an inertia of the motor, J o inertia of the optical element, θ is an angle of rotation, and K is a stiffness of the tensional mode, and “{umlaut over ( )}” indicates the second derivative with respect to time.
