提出了一种基于电致变色聚合物聚（3，4-乙撑二氧噻吩）的微电光虹膜。两个环形同心聚合物嵌在一个透明的电化学电池段形成微虹膜。当施加外部电压时，聚合物层会改变其吸收。该虹膜装置受益于没有任何机械移动部件。这使得非常纤薄的设计成为可能，这适用于小型集成相机系统。在操作期间，聚合物保持其吸收状态而不消耗功率。其最高1.5 V的低驱动电压有利于电池供电应用。光圈对焦深和传输控制的影响以及其动态行为将得到解决。
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.
