| 摘要 |
The invention relates to a displacement device for a number of objects, method for production of the displacement device and device for splicing a number of optical waveguides, whereby the displacement device (100), by means of which a number of objects may be simultaneously positioned along a displacement direction, comprises a base element (101) and several piezoelectrical stack arrangements (102). Each stack arrangement (102) is connected on one side to the base element (101). On another side, each of the stack arrangements (102) may be coupled to a holder element, provided for holding one of the objects. The stack arrangements (102) comprise a layered construction in the displacement direction of an alternating piezoelectric layer (103) and an electrically conducting electrode (104). The stack arrangements (102) may be varied in the length thereof along the displacement direction, individually and independent of the displacement of the other stack arrangements (102), by application of a suitable voltage to the electrodes. Objects may be positioned with the displacement device which are arranged at a small separation from each other of, for example, 0.10 mm, due to the small spatial dimensions thereof. |
