This communication presents the results obtained for decreasing the response time of electrowetting-based real
time focus correctors (liquid lenses). In order to provide a compact iris biometric system demonstrator, we have
achieved a response time at 90% of 7.5 ms for a change in focalization from 0 diopter to 10 diopter with a liquid
lens having an aperture of 1.9 mm. We have used a hydrodynamic fluid reorganization model to predict the
features of these fast liquid lenses and evaluated the sensivity of the response time to the different conception
parameters.
