| 中文摘要 | 针对强度关联成像遥感探测中存在的成像速度受到参考臂图像采集速度限制的问题,研究了一种基于随机相位板扫描的可重复赝热光源。通过产生可重复使用的散斑,省去成像过程中参考臂的实时采集。建立了散斑重复性评价函数,并数值模拟分析了使用可重复散斑对关联成像质量的影响,给出了在不影响成像质量的情况下所允许的激光强度抖动和扫描定位精度。实验分析了此可重复赝热光源的性能指标。实验结果表明,在发射速率为4000 frames/s时,赝热光源的激光强度抖动及扫描定位精度均满足要求,散斑相关系数可达到0.97以上,成像分辨率可达到衍射极限,证实了此可重复赝热光源的可行性。 |
| 英文摘要 | To solve the problem that the imaging speed is limited by the reference arm acquisition in remote sensing experiment based on correlated imaging, a repeatable pseudo-thermal light based on random phase plate scanning is proposed. The repeatable laser speckles are produced so that reference arm acquisition is not necessary in imaging process. Repeatability evaluation function is established and the influence of repeatability on image quality are numerically analyzed. Laser intensity jitter and positioning accuracy are pointed out to make sure that the image quality is not affected. The performance of the repeatable pseudo-thermal light is verified, and at the emission velocity of 4000 frames/s, the correlation coefficient can reach more than 0.97 with intensity jitter and positioning accuracy satisfying. The feasibility of the repeatability of pseudo-thermal light is approved and imaging resolution can reach the diffraction limit. |
