Light-powered gyroscope is world's smallest
San Francisco CA (SPX) Apr 09, 2015 - A pair of light waves - one zipping clockwise the other counterclockwise around a microscopic track - may hold the key to creating the world's smallest gyroscope: one a fraction of the width of a human hair. By bringing this essential technology down to an entirely new scale, a team of applied physicists hopes to enable a new generation of phenomenally compact gyroscope-based navigation systems, ... more
