Micro scanner device and method for controlling micro scanner device

摘要

A mirror axis (MA) is displaced by deformation of a holder (HD) and with resonance of an optical scanner (LS) itself according to the frequency of a voltage applied to a piezoelectric element (PE). The frequency of the applied voltage for causing a resonance deforms the holder (HD) so as to generate at least one node intersecting with respect to the length of the holder (HD) itself.
