Abstract
This work proposes an innovative solid-state variable micro aperture with no moving component. The aperture size can be varied by the change of applied voltage. PDLC (polymer dispersed liquid crystal) plays an important role in tunability of this device. By combing a micro dome structure and the PDLC, the tum-on threshold voltage at a farther radial position to the aperture center can be made higher than that at a closer position. This way, the aperture can open gradually as increasing the voltage.
