Auxiliary free space optical communication project to ensure continuous transfer of data for DAG the 4m telescope. Paper presented at the Proceedings of SPIE - The International Society for Optical Engineering, 9912, 1-8. doi:10.1117/12.2234388978151060203897815106020450277-786X1996-756Xhttps://hdl.handle.net/11729/1168http://dx.doi.org/10.1117/12.2234388The continuity of the amount of data that the 4m DAG (Eastern Anatolia Observatory in Turkish) telescope will produce and transfer to Ataturk University is critical not to jeopardize the science programs. Though the fiber optics and radio link infrastructures are in place, these systems are still volatile against earthquakes, and possible excavation damages. Thus the 4m DAG telescope will be equipped with a free space optical communication system to ensure the continuity of the data transfer as a backup system. In order to cope with the disturbances introduced by the atmospheric turbulence, the transceiver FSO system will be equipped with a wavefront corrector. In this paper, the Cassegrain optical design, and working principle of this system as well as expected performance analyses will be presented.eninfo:eu-repo/semantics/closedAccessFSO CommunicationLaserAtmospheric turbulenceData transferLasersOptical designRadio linksTelescopesVision aidsAtmospheric compensationEastern AnatoliaFree Space Optical communicationFree space optical communication systemsPerformance analysisScience programsWavefront correctorOptical communicationTurbulenceSystemsAuxiliary free space optical communication project to ensure continuous transfer of data for DAG the 4m telescopeConference Object991218N/AWOS:0003877479002112-s2.0-8499695524010.1117/12.2234388N/A
