Abstract
An optical module includes a first optics group, a second optics group, and an image sensor, wherein the first optics group and second optics group are configured to provide an image having a focus and a magnification to the image sensor. In some embodiments of the present invention, a first optics assembly includes a first optics group coupled to a threaded portion of a first lead screw so that translation of the first lead screw results in translation of the first optics group along an axis of the first lead screw, a first actuator for rotating the first lead screw; and a first sensing target configured to permit detection of rotation of the first lead screw. In some embodiments of the present invention a second optics assembly includes a second optics group coupled to a threaded portion of a second lead screw so that translation of the second lead screw results in translation of the second optics group along an axis of the second lead screw, a second actuator for rotating the second lead screw, and second means for sensing configured to detect rotation of the second lead screw.
