Abstract:
1. A multi-DOF (degree-of-freedom) of positioning device for alignment a first optic fiber that is supported on a first optical fiber holder with a second optic fiber, and the multi-DOF (degree-of-freedom) of positioning device comprising: a main base; a fixed base connected to the main base; a translational Y-axial element moveably mounted on the fixed base along a first axis; a translational X-axial element moveably mounted on the translational Y-axial element along a second axis perpendicular to the first axis; two first spring-mounted electromechanical actuating units mounted on the fixed base to make the translational Y-axial element move relative to the fixed base along the first axis; two second spring-mounted electromechanical actuating units mounted on the translational Y-axial element to make the translational X-axial element move relative to the translational Y-axial element along the second axis; an elevating device moveably mounted on the main base along a third axis perpendicular to the first and the second axes; two third spring-mounted electromechanical actuating units mounted on the elevating device to move the elevating device relative to the main base along the third axis; a rotational angle-adjusting assembly mounted on the translational X-axial element and having a capability of rotating relative to the first, the second and the third axes; and a second optical fiber holder attached to the rotational angle-adjusting assembly and adapted to support the second optic fiber to align with the first optic fiber.
