We suspect there are three kinds of people in the world. People who have access to a Michelson Interferometer and are glad, those who don’t have one and don’t know what one is, and a ...
Abstract: A microwave photonic structure for measuring the frequency of an RF signal received by an antenna is presented. The main component is an unbalanced Michelson interferometer (UMI) composed of ...
Ten years ago, astronomers made an epic discovery with the Laser Interferometer Gravitational-Wave Observatory. Cosmology hasn’t been the same since, and it might not stay that way much longer. Out ...

The Korea Research Institute of Standards and Science has successfully developed a length measurement system that achieves a level of precision approaching the theoretical limit allowed by quantum ...
Two changes improved the apparatus over the one used at Potsdam [in 1886]. Morley suggested floating the heavy sand stone slab bearing the optical parts on mer cury. The stone, about 5 feet square, ...
University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...
