Abstract
A high-precision scanning device () comprises a first linear scanner () for providing scanning movements along a first linear scanning axis (). The first linear scanner comprises a first base frame (), a first scanning frame (), two mutually parallel first piezoelectric bending plates (A,B), and two first hinge joints (A,B) having two first hinge axes (A,B), respectively. Under influence of synchronic piezoelectric operation of the two first piezoelectric bending plates, the first scanning frame is being synchronically moved relative to the first base frame along said first linear scanning axis. The scanning device is compact, especially nearby the working areas where the precise scanning movements have to be performed, so that the device can be operable in very tiny working areas.
