Abstract: A control method of the magnetic actuator system includes the following steps. A first initial orientation step is to move a magnetic actuator to a first position in accordance with a first position signal, and generate a first position sense signal by a position sensor. A second initial orientation step is to move the magnetic actuator to a second position in accordance with a second position signal, and generate a second position sense signal by the position sensor. An orientation step is to perform an interpolation in accordance with the above signals and a target position signal to obtain a target position sense signal. A moving step is to move the magnetic actuator to an actual position in accordance with the target position signal, and output an actual position sense signal by the position sensor. An adjustment step is to move the magnetic actuator to a target position in accordance with the target position sense signal and the actual position sense signal.

Abstract: A magnetic actuator. A yoke includes a first opening and a second opening, a frame, and a path. A first magnet is disposed in the first opening in the vicinity of the frame. A second magnet is disposed in the second opening in the vicinity of the frame. A coil comprises a wire surrounding the path. A light shield is connected to an end of the coil. A guiding element disposed outside the path is connected to an end of the coil. When current passes through the coil, the coil moves along the path by magnetic induction between the first magnet and the second magnet such that the iris diaphragm is adjustable by the light shield. When there is no current through the coil, dynamic force produced by the guiding element returns the light shield to its original position.

Abstract: A magnetic actuator. The magnetic actuator comprises a first magnet, a second magnet, a first yoke, and a first coil. The second magnet is arranged axially with respect to the first magnet with repulsion therebetween. The first yoke is disposed between the first magnet and the second magnet, and the magnetic field lines produced by the first magnet and the second magnet extend from the first yoke. The first coil surrounds and corresponds to the first yoke. When a current is occurred in the first coil, the magnetic force generated between the first magnet and the second magnet will actuates the first coil to move axially with respect to the first and second magnets.

Abstract: A wavelength stabilizing apparatus utilized in an optical communication system for controlling a light wave output from a tunable optical component is disclosed. The wavelength stabilizing apparatus includes a coarse-tuning element, a fine-tuning element, and a servo element. When the wavelength stabilizing apparatus is used, the light wave output from the tunable optical component is directed into the coarse-tuning element and the fine-tuning element, respectively, and then transformed into electric signals to be received by the servo element. Particularly, the electric signals from the coarse-tuning element are served as basis for coarse-tuning and channel recognition of the light wave output from the tunable optical component while the electric signals from the fine-tuning element are served for fine-tuning and servo control of the light wave output from the tunable optical component. These electric signals are also processed with a logical operation to obtain a control signal for controlling the tunable optical component.
