Existing liquid lense optical focusing strategies use liquid lenses after transient oscillations have dampened. The challenge with this existing liquid lens approach is two-fold. The first issue is to overcome the liquid inertia to enable a rapid state change, and the second, is to minimize the time it takes for transients induced during stoppage to Subside. Many systems use brute force activation methods to effect a shape change, creating undesired transient motion, which then necessitates a high-dissipative media to dampen them out. This invention is directed to an oscillating liquid lens that offers high quality images with quick changes in focal length for adaptive imaging systems. The design couples two droplets via a cylindrical hole, and oscillates them using a small pressure source (like a tiny speaker), continuously changing the lens shape. At resonant frequency, the motion can be sustained with very little energy input. The depth of focus can be quickly changed by altering the timing of the image capture to synchronize with the oscillations of the lens.
