We analyze the potential efficiency of laser beam projection onto a remote object in atmosphere with incoherent and coherent phase-locked conformal-beam director systems composed of an adaptive array of fiber collimators. Adaptive optics compensation of turbulence-induced phase aberrations in these systems is performed at each fiber collimator. Our analysis is based on a derived expression for the atmospheric-averaged value of the mean square residual phase error as well as direct numerical simulations. Operation of both conformal-beam projection systems is compared for various adaptive system configurations characterized by the number of fiber collimators, the adaptive compensation resolution, and atmospheric turbulence conditions.
我们使用由光纤准直器自适应阵列组成的非相干和相干锁相共形光束导向系统，分析了激光束在大气中投射到远程物体上的潜在效率。在这些系统中，每个光纤准直器都对湍流引起的相位像差进行自适应光学补偿。我们的分析基于均方残余相位误差的大气平均值的推导表达式以及直接数值模拟。针对以光纤准直器数量、自适应补偿分辨率和大气湍流条件为特征的各种自适应系统配置，比较了两种共形光束投影系统的运行情况。
