Lens actuator

摘要

A flexible lens may be actuated to change its focal length by a deployable lens actuator. The lens actuator translates a rotational motion of an outer frame into a linear radial motion of a plurality of linear elements. The linear elements have fixed pins, which may be slidably coupled to cam pockets in the outer frame. The cam pockets have a gradually varying distance from the center of the outer frame. The rotation of the outer frame thus drives the cam pockets to slide about the pins, thereby causing radial motions of the linear elements. The linear elements stretch a flexible lens, thereby changing a curvature of the flexible lens.

1. A deployable device, comprising:
a generally planar outer frame configured to rotate about a center point; a plurality of linear elements configured to move radially relative to the center point as driven by the rotation of the outer frame; and a plurality of attachment portions coupled to proximal ends of the linear elements, wherein the attachment portions are configured to be coupled to a flexible lens material, wherein the outer frame has one or more first grooves thereon, wherein the one or more first grooves have a gradually varying distance from the center point, and wherein the plurality of linear elements each have one or more fixed pins slidably coupled to one of the one or more first grooves.
