  • Patent number: 7715106
    Abstract: A liquid-control optical element is provided herein. The optical element includes two liquids with different phases. The two liquids are immiscible and have different optical index. By applying a voltage through electrodes to form an electric field, the slope of an interface between the two liquids is changed. The purpose of changing the slope is to change the shape of the interface or the moving or rotating direction. Thus, according to the law of total internal reflection or the law of refraction, the liquid-control optical element can be used as a liquid shutter device, or a liquid scanner device if a scanning is performed after penetrating the element.
