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。
In order to overcome the problem of image degradation caused by the relative motion between the target and the system, a shift compensation of the intensity distribution of the light field based on the reference arm detector is proposed to improve the moving target intensity Associated imaging resolution program. The theoretical and experimental results show that the high resolution image of the moving target can still be obtained by using the intensity correlation imaging technique by compensating the light field intensity recorded by the reference arm detector. The effects of detection noise on the quality of moving target intensity correlation imaging reconstruction are discussed respectively for the intensity-dependent linear reconstruction and the sparse-constraint nonlinear reconstruction. In addition, the advantages and disadvantages of the described technique and the conventional motion blur removal technique are compared.
