Abstract:
|
New, affordable adaptive compensation methods and technologies can help to improve substantially the
performance and reliability of coherent optical systems in the atmosphere. The use of adaptive optics to mitigate
turbulence-induced phase fluctuations in receivers employing coherent detection is poised to reduce performance
penalties enabling a more sensitive generation of coherent instruments and applications.
In this work we describe the implementation of an optical coherent receiver that uses phase compensation and
adaptative optic techniques, as well as digital architectures for signal processing and control. We show experimentally
the viability of the approach to improve the efficiency and sensitivity of the receiver. Both free-space optical
communications and coherent lidar systems may benefit from use of the methods and techniques derived from this
research. |
