DESCRIPTION

You will hear about an exciting new micromirror array designed and being prototyped at LLNL. It promises faster, more accurate motion and larger range than what is currently on the market. The new design will enable advanced applications in areas such as 3D image projection and high-speed focusable LIDAR, among others.
