  • Optical control device having a controller that controls track movement of a driven member through a drive unit with reflecting regions
    Patent number: 6972404
    Abstract: An optical control device includes a drive member formed with a plurality of reflecting regions along a second track and movable along the second track for driving a driven member to move along a first track. An optical unit emits a light beam that is incident upon an aligned reflecting region, and receives a light beam that was reflected by the aligned reflecting region to generate an electrical output. A controller determines actual positions of the drive member on the second track and the driven member on the first track, and controls the drive member to move along the second track so as to dispose the driven member at a desired position on the first track.
