Abstract
An electromechanical resonator is disclosed for use in optical scanning systems. The resonator comprises a torsionally resonant system including a torsion rod having one end fixed to a nodal zone member and an oscillatory mass at the free end. A flexurally resonant system includes a pair of oppositely disposed flexure arms extending transversely of the torsional axis and having their inner ends fixed to the nodal zone member. The nodal zone member is suspended by a coupling spring from a frame member and the coupling spring permits energy transfer from the flexurally resonant system to the torsional resonant system through nodal zone member. The resonant systems are maintained in oscillation by electrodynamic means coupled with the flexure arms.
