“…These include: spatial transmitter/receiver diversity [9] [10]; adaptive beam forming based on the wave front phase error measurement and settings of the opposite phase aberration on the beam by a deformable mirror [11]; wavelength diversity [12], multiple-beam communication [13] and novel modulation techniques [14]. SIMO (singleinput multiple-output) or MIMO (multiple-input multiple-output) optical channels have been studied for more than 40 years [15,16] and measurements of SIMO systems were reported in numerous papers, e.g. between terrestrial station and satellite [17], ground station and aircraft [18] or laboratory experiments [13,19].…”

Free-Space Optical (FSO) communications link performance is highly affected when propagating through the time-spatially variable turbulent environment. In order to improve signal reception, several mitigation techniques have been proposed and analytically investigated. This paper presents experimental results for the route diversity technique evaluations for a specific case when several diversity links intersects a common turbulent area and concurrently each passing regions with different turbulence flows.

“…The atmospheric turbulence affecting optical beams can be efficiently mitigated via various techniques: source partial coherence, [1][2][3][4][5] aperture averaging, [6] sparse aperture detectors, [7,8] wavelength diversity, [9] and source temporal variations. [10] Recently, it was also proposed via analytical calculations [11] and simulations [12,13] that the polarization diversity can be efficient for solving this problem.…”

It is experimentally demonstrated that the class of partially coherent, partially polarized optical beams can be efficiently used for reduction in scintillations on propagation through turbulent air. The experiment involving the electromagnetic beam generation and its interaction with turbulent air simulator is discussed in details. The collected data is in solid agreement with the recently published theoretical predictions.

Net-centric warfare in todays dynamically changing military environments and the need for low-cost gigabit intra-city communication present severe challenges for current free-space optical systems. Enabled by high-speed electronics and advances in wavefront control, we develop an architecture that provides free-space coherent optical links with information capacity, security, network robustness and power management performance that exceed the current state-of-the-art, including commercially deployed systems, R&D test-beds, and alternative theoretical architectures proposed. The deleterious effects of the turbulent atmosphere are mitigated with several diversity transmitters and receivers. We allow the phase and the amplitude of each transmitter to be controlled independently and assume, through coherent detection, that the phase and amplitude of the received wave is measured. Thus we can optimally allocate transmit power into the diffraction modes with the smallest propagation losses to increase channel capacity and mitigate turbulence-induced outages. Additionally, spatial mode modulation and rejection provides robust communication in the presence of denial of service via interference by adversaries with a priori knowledge of the system architecture. Some possible implementations of this system are described. New results, including asymptotic singular value distribution, expected bit error rate, interference performance, and performance in the presence of inhomogeneous turbulence, are given. Finally, performance of this system is compared with the performance of optical diversity systems without wavefront control and optical systems without diversity, both current state-of-the-art systems.
