a light beam source;
a vibrating element having at least two modes of vibration respectively in at least
two planes, said vibrating element having respective resonant frequencies associated with
each of the modes of vibration which are not integral multiples of each other;
means for driving said vibrating element at substantially its resonant frequency in
each of said two modes to cause it to thereby rotate said vibrating element in said at least
two planes; and
a scanning surface which receives and reflects a light beam from said source and
which moves in association with movement of said vibrating element.
