In this paper, 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.

在调制后向反射器自由空间光通道中使用微角立方反射器阵列进行波前补偿

在本文中，微角立方反射器阵列（MCCRA）被认为是调制后向反射器（MRR）自由空间光（FSO）通道中的光学后向反射器，其波前补偿伴随着伪相位共轭光返回波在通过理论分析和波动光学 (WO) 模拟研究了双通传播。通过WO模拟，我们展示了回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、斯特列尔比和回波的闪烁指数的影响。此外，我们研究了由 MCCRA 的相位误差和光束的斜入射引起的限制。最后，在实验室大气室中进行的实验证明了波前补偿。
