摘要：
We introduce a closed-loop pressure control of a single chamber adaptive fluidic membrane lens with an integrated piezoelectric bending actuator. For this purpose a pressure sensor is integrated into the lens and allows for a measurement of the chamber pressure as a function of the refractive power. The linear relation between pressure and refractive power allows to eliminate the typical hysteresis effects of piezo actuators.
