Dissemination of precise frequencies over a free-space optical link
Original language description
The dissemination of precise time and frequencies has an irreplaceable role in many applications (experiments in the metrology of time and length, security of critical infrastructures, synchronisation of navigation and positioning systems, telecommunications, sensors of physical quantities and others). In cases where optical fibre links cannot be used, we must deploy a different transmission type. This work studies the possibilities of distributing stable optical frequencies over free-space optical (FSO) links, and it describes pilot experiments of optical frequency coherent transfer between ISI CAS (optical source, optical fibre links, data processing) and FEEC BUT (development and operation of FSO units).
