Adaptive liquid lens actuated by liquid crystal pistons
Optics Express, 2012 An adaptive liquid lens actuated by liquid crystal (LC) pistons is demonstrated. It adopts fluid pressure introduced by the reciprocating movement of LC droplets to regulate the liquid-air interface which, in turn, changes the optical power of the resultant liquid lens.

Dispersion compensation by a liquid lens (DisCoBALL). [PDF]
Appl Opt, 2019 We present dispersion compensation by a liquid lens (DisCoBALL), which provides tunable group-delay dispersion (GDD) that is high speed, has a large tuning range, and uses off-the-shelf components. GDD compensation is crucial for experiments with ultrashort pulses.

Dielectrically actuated liquid lens
Optics Express, 2007 A packaged liquid lens driven by the dielectric force was demonstrated. The liquid lens consisted of a low dielectric constant droplet and a high dielectric constant sealing liquid. The two non-conductive liquids were sealed in a chamber under the condition of iso-density.
