Abstract
A lens cleaning device includes: a housing shaped to fit over an end of a camera lens; a wiper movably attached to the housing, the wiper movable across the housing from a first position adjacent a first side of the housing to a second position adjacent a second side of the housing; and at least one SMA wire mechanically associated with the wiper. When the SMA wire is activated, the wiper is moved between the first position and the second position of the housing such that the wiper sweeps debris from a field of view of the camera lens.
