We present a mathematical model and provide an analysis of optical beam director systems composed of adaptive arrays of fiber collimators (subapertures), referred to here as conformal optical systems. Performances of the following two system architectures are compared: A conformal-beam director with mutually incoherent output laser beams transmitted through fiber collimators (beamlets), and a corresponding coherent system whose beamlets can be coherently combined (phase locked) at a remote target plane. The effect of the major characteristics of the conformal systems on the efficiency of laser beam projection is evaluated both analytically and through numerical simulations. The characteristics considered here are the number of fiber collimators and the subaperture and conformal aperture fill factors, as well as the accuracy of beamlet pointing.
我们提出了一种数学模型，并对由光纤准直器（子孔径）的自适应阵列组成的光束导向系统进行了分析，在此将其称为共形光学系统。比较了以下两种系统架构的性能：一种是共形光束导向器，其通过光纤准直器（子光束）传输相互不相干的输出激光束；另一种是相应的相干系统，其子光束可在远程目标平面上进行相干组合（锁相）。通过解析和数值模拟评估了共形系统的主要特性对激光束投射效率的影响。这里考虑的特性包括光纤准直器的数量、子孔径和共形孔径填充因子，以及子光束指向精度。
