1. An image stabilization system, comprising:

  • a first pair of liquid lens cells offset from each other along a common axis and offset from each other along a first direction non-parallel to the common axis;

    a second pair of liquid lens cells offset from each other along the common axis and offset from each other along a second direction non-parallel to the common axis, where an offset from the common axis of each of the second pair of liquid lens cells is in a direction substantially different from an offset from the common axis of each of the first pair of liquid lens cells, and the magnitude of the offset from the common axis of each of the second pair of liquid lens cells is greater than the magnitude of the offset from the common axis of each of the first pair of liquid lens cells, and where each liquid lens cell in the first and second pairs of liquid lens cells comprises contacting liquids and a contacting surface between the contacting liquids having a variable shape;

    a sensor configured to detect movement of at least one lens element; and

    a controller configured to vary the shape of the contacting surfaces of the liquid lens cells in the first and second pairs to compensate for movement of the at least one lens element and provide stabilization of an image formed by radiation that is delivered to an image side space.
