摘要：

We present a micro-electrooptical iris based on the electrochromic polymer poly(3,4-ethylenedioxythiophene). Two ring-shaped concentric polymer-segments embedded in a transparent electrochemical cell form the micro iris. The polymer layers change their absorption when an external voltage is applied. This iris device benefits from the absence of any mechanically moving part. This renders a very slim design possible, which is suited for small integrated camera systems. During operation the polymer maintains its absorbing state without power consumption. Its low driving voltage of maximum 1.5 V is beneficial for battery powered applications. The impact of the iris on the depth of focus and transmission control as well as its dynamical behavior will be addressed.
