Abstract
A system and method for adjusting the focus or zoom of a microfluidic lens assembly is described. In some cases, the system adjusts the focal length of a microfluidic lens assembly in order to compensate for the effect of temperature on the lens assembly. In some cases, the system dynamically adjusts the lens assembly in order to provide auto focusing of a bar code scanner. The system may use an open-loop system where one or more look-up-table(s) are used to quickly provide a compensation value.
