ABSTRACT:
A fine positioning device is formed of a central rigid portion, a first set of outwardly-extending portions extending symmetrically along a first axis from the central rigid portion, a second set of outwardly-extending portions extending symmetrically from the central rigid portion along a second axis which is perpendicular to the first axis, a first set of parallel flexible-beam displacement mechanisms provided symmetrically to each other with the first set of outwardly-extending portions respectively to produce translational displacements along the second axis, and a second set of parallel flexible-beam displacement mechanisms provided symmetrically to each other with the second set of outwardly-extending portions respectively to produce translational displacements along the first axis. Three set of radial flexible-beam displacement mechanisms are provided to produce angular displacements about three axes.
