Abstract
We present two different piezo-actuated adaptive prisms with apertures ≥8 mm based on a tiltable glass window on top of an optical fluid. In the first prism, we realized a simple monoaxial scanner based on a lever principle. In our second design, we extended the scanning to two axes using three individually controllable piezo cantilevers. We were able to prove the concept for continuously adjustable variable prisms and achieved a tilt angle up to ±3.7° with a response time of 36 ms.
