The additional mirror is made of a superflexible material -- plastic, in the Johns Hopkins device. A light sensor monitors a reference star within the telescope's field of view and looks for the shimmering caused by currents in the atmosphere. When the sensor detects disturbances, it sends signals to electrodes flanking the plastic mirror. The electrodes create electric fields that make the plastic bulge or dip, canceling out the flicker. Both the Hawaii and Johns Hopkins...
