Exoplanets to medical tests: Tiny frequency devices open up new applications
(PHYSorg.com Physics)

Accurately measuring frequencies of light is required for timekeeping. It`s also a critical component in many science experiments and technologies, from military defense to detecting air pollution, tests of fundamental physics to the detection of exoplanets. `There are few human enterprises that are both more fundamental and more important for technology,` says Curtis Menyuk, professor of Computer Science and Electrical Engineering at UMBC.
