  • Multi-fluid lenses and optical devices incorporating the same
    Patent number: 7324287
    Abstract: The present invention provides a variety of fluid lens configurations that enable beam steering and focus adjustment. For example, according to one aspect of the present invention, a fluid lens is configured such that an optical signal may propagate from an input side of the lens to an output side of the lens along an axis of optical propagation extending through first and second lens surfaces defined by the immiscible fluids of the lens. Respective tunable lens surfaces are formed along the interfaces between the immiscible fluids and an external signal is capable of changing the shape of those surfaces. Because the two lens components forming the lens surfaces are laterally offset, the focal length and beam steering of the lens can be tuned by varying the shape of the surfaces. Additional embodiments are disclosed.
