摘要
开展了强度关联成像领域中对于运动目标成像的研究,为了克服目标与系统之间的相对运动引起的图像退化问题,提出了基于参考臂探测器记录的光场强度分布平移补偿进而提高运动目标强度关联成像分辨率的方案。理论和实验结果表明:通过对参考臂探测器记录的光场强度分布进行平移补偿,利用强度关联成像技术仍然可以获取运动目标的高分辨率图像。针对强度关联线性重构和稀疏约束非线性重构算法,分别讨论了遥感探测应用过程中探测噪声对运动目标强度关联成像重构质量的影响。此外,比较了所述技术与现有去运动模糊技术的优缺点。
Abstract
The moving target imaging in the field of ghost imaging is researched. In order to overcome the imaging degradation caused by relative motion between imaging system and target, a method of translation compensation of light intensity distribution recorded by the reference detector is proposed so that the resolution of ghost imaging for moving target can be improved. Both theoretical and experimental results suggest that ghost imaging technique can obtain high-resolution imaging of moving target by the proposed method of translation compensation. According to the application of remote sensing, the influence of detection noise to ghost imaging for moving target is discussed based on intensity correlation linear reconstruction and nonlinear sparsity constraints reconstruction algorithms, respectively. The advantages and disadvantages of both the proposed technique and existing motion-deblurring techniques are also discussed.
