Method and apparatus for adjusting position of optical element |
摘要 |
An apparatus for adjusting a position of an optical element is disclosed. The apparatus includes: a support; a movement unit for supporting an optical element and being movable relative to the support; a magnet unit; a coil unit for generating a magnetic force for moving the movement unit when an electrical signal is applied; a sensor unit disposed in a position corresponding to the magnet unit for detecting a relative position of the movement unit with respect to the support; a locking unit for limiting or allowing movement of the movement unit; and a controlling unit connected to the coil unit for controlling the coil unit and determining whether the movement unit is in a state where movement of the movement unit is limited by the locking unit based on a signal output from the sensor unit. |
