Paper Abstract

The Optical Communications Group of the German Aerospace Research Establishment (DLR) has investigated the feasibility of a fiberless receiver telescope for high sensitive coherent optical space communication, resulting in an elegant Pointing, Acquisition and Tracking (PAT) concept. To demonstrate the feasibility of this new concept, an optical receiver terminal that coherently obtains both the spatial error signal for tracking and the data signal with only one set of detectors has been built. The result is a very simple and compact setup with few optical surfaces. It does not require fibers for superpositionning and is capable to compensate for microaccelerations up to about one kilohertz. Keywords: free-space optical communication, coherent optical receiver terminal, satellite vibration compensation, fiberfree heterodyning, Pointing, Acquisition and Tracking
