The amount of scientific data to be transmitted from deep-space probes is very limited due to radio-frequency (RF) communications constraints. Free-space optical communication can alleviate this bottleneck, increasing data rate while reducing weight,

In this work, a technique to generate aspherical liquid crystal lenses with positive and negative optical power is experimentally demonstrated. The main enabling element is a micro-metric electrode with variable spatial size. This produces a decreasi
