In this article, the micro corner-cube reflector array (MCCRA) is considered as the optical retroreflector in the modulating retroreflector (MRR) free-space optical (FSO) channel and its wavefront compensation accompanying with the pseudo phase conjugate optical return wave in the double-pass propagation is investigated by the theoretical analysis and wave-optics (WO) simulation. By WO simulations, we show the impacts of the shape and size of the retroreflector cell, the whole aperture size of the MCCRA, the turbulence condition on the beam spot, the Strehl ratio and the scintillation index of the return wave. Also, we investigate the limitations caused by the phase errors of the MCCRA and the oblique incidence of the optical beam. Finally, the wavefront compensation is demonstrated by the experiments conducted in a laboratory atmospheric chamber.

调制后向反射器自由空间光通道中微角立方反射器阵列的波前补偿


本文将微角锥反射器阵列（MCCRA）视为调制后向反射器（MRR）自由空间光学（FSO）通道中的光学后向反射器，及其与伪相位共轭光回波相伴的波前补偿。通过理论分析和波动光学（WO）模拟研究了双程传播。通过WO模拟，我们展示了后向反射器单元的形状和尺寸、MCCRA的整个孔径尺寸、束斑的湍流条件、返回波的斯特列尔比和闪烁指数的影响。此外，我们还研究了 MCCRA 的相位误差和光束倾斜入射引起的局限性。最后，通过在实验室大气室中进行的实验证明了波前补偿。
