摘要

提出了基于现场可编程逻辑门阵列(FPGA)硬件控制平台将空间激光耦合至单模光纤(SMF)的自适应耦合技术。将自适应光纤耦合器作为激光接收器件和像差校正器件, 使用基于随机并行梯度下降(SPGD)算法的FPGA硬件控制平台实现SMF端面对聚焦光斑的自适应跟踪, 算法的双边迭代速率达到了3 kHz。实验结果表明, 该控制系统可补偿SMF接收端面最大约9 μm的静态对准偏差(对应空间光束的最大可校正静态角偏差为600 μrad), 对于模拟大气湍流造成的耦合效率下降具有150 Hz的校正带宽。

Abstract

An adaptive coupling technology for space laser coupling to single-mode fiber (SMF) based on the field programmable logic gate array (FPGA) hardware control platform is proposed. An adaptive fiber coupler is employed as the laser beam receiver and the aberration corrector. The adaptive tracking of the SMF′s end plane for the focused spot is implemented by the FPGA hardware control platform based on stochastic parallel gradient descent (SPGD) algorithm with the bilateral iteration rate of 3 kHz. The experimental results show that the maximum static alignment error (about 9 μm) of the SMF′s end plane (corresponding to the space beam′s maximum corrective static angle deviation of 600 μrad) is efficiently compensated by the control system, and correction bandwidth about 150 Hz is achieved under the simulated atmospheric turbulence.
