Non-standard phase manipulation with a liquid lens

Research output: Contribution to conferencePosterScientific


Liquid lenses are an emerging technology, that allows focal switching without any moving parts. While standard liquid lenses focus on tuning the defocus aberration, higher order aberrations shift into the focus of the current research. We propose a method using standing waves on a liquid lens to design more complex phase fronts. Similar to common speaker membranes, it is possible to create a large variety of different surface functions on the liquid’s surface by controlling the AC input voltage. The created phase fronts are circularly symmetric and can for example take the shape of spherical aberrations. Liquid lenses might therefore be used as a cheap tuneable phase manipulator for beam shaping, or image correction.
