Numerical simulations of Nicolao Lima just appeared in the journal Optics Express

In this article, we describe the novel concept of an electrostatically tunable adaptive liquid microlens with 100 individually addressable electrodes that generate an (almost) arbitrary distribution of electrical stresses on the liquid surface.

This approach turns out to be very flexible and allows to address specific types aberrations (spherical, cylindrical, coma) individually by choosing appropriate excitation patterns of the electrodes. The numerical implementation of the model enables a systematic parameter study to optimize the excitation patterns and – if combined with a feedback mechanism – should allow for online wavefront shaping.
