Abstract (en)
[origin: WO0128137A1] A system and method for free space optical communication include at least one reconfigurable terminal (30) using dual-wavelength operation for isolation between transmitted and received signals in combination with polarization switching to separate and steer the transmitted and received signals to and from corresponding transmitters (40) and receivers (48). The polarization based switching provides wavelength independent beam steering to facilitate interchanging of wavelengths for transmitted and received signals. A controllable or passive polarization changer (56) such as a wave plate or polarization rotator allows the communication terminal (30) to be reconfigured without also requiring the repositioning and associated precision alignment of beam steering optics (54, 62, 66).
