Abstract:
1. A method of using a micro-mirror device having a reflective element, a pair of electrodes spaced from the reflective element, and a dielectric liquid disposed at least between the reflective element and the pair of electrodes, said method comprising the steps of: electrically coupling to the pair of electrodes an operational amplifier having an output for coupling to at least one of the pair of electrodes and having inverting and non-inverting inputs; electrically coupling the reflective element to the inverting input of the operational amplifier to provide feedback; and applying an analog positioning signal to the non-inverting input of the operational amplifier, whereby the reflective element is positioned at a selected position within a continuous range between a first position and a second position in response to the applied analog positioning signal.
