| 摘要 |
The present invention relates to an optical assembly capable of sensing the rotational position of an optical member. The optical assembly comprises: an optical member; a support unit arranged to support the optical member such that the optical member rotates in a first axis direction, a second axis direction or a combined direction of the first axis and the second axis; a power providing unit which provides power for rotating the optical member; and a position sensing unit including a plurality of optical sensors to sense the rotational position of the optical member. |
