Full text linkXY displacement device
No full textAn XY-displacement device (1) with a four-fold symmetry comprises a reference frame (10); an object mount (20) for holding an object (22) to be displaced; an X-manipulator (100) coupled between the reference frame (10) and the object mount (20), which provides a rigid coupling between the object mount (20) and a piezoelectric X-actuator (140), allows a Y-displacement of the object mount (20) relative to the reference frame (10), and counteracts a Z-displacement of the object mount (20) relative to the reference frame (10); ; and a Y-manipulator (200) coupled between the reference frame (10) and the object mount (20), which provides a rigid coupling between the object mount (20) and a piezoelectric Y-actuator (240), allows an X-displacement of the object mount (20) relative to the reference frame (10), and counteracts a Z-displacement of the object mount (20) relative to the reference frame (10).Applied Science
