Optical Time Distributor and Process for Optical Two-Way Time-Frequency Transfer

NIST Inventors
Laura Sinclair, Nathan R Newbury, William C. Swann and JD Deschenes
Patent Description The invention is a method to compare and synchronize "clocks" (i.e. local timescales) through optical links across free space, which include open air paths through the atmosphere to other terrestrial sites or to satellites, as well as satellite-to-satellite paths. The challenge is
