设计一种针对粗糙表面目标的基于稀疏限制的鬼成像(GISC)实验装置,研究并分析接收系统的数值孔径与粗糙目标尺寸对GISC成像性能的影响。结果表明,粗糙目标的GISC成像质量与接收系统的数值孔径和目标尺寸均呈正相关。本研究可以为GISC装置中接收系统的光路设计提供重要参考。

An experimental setup of ghost imaging via sparsity constraints (GISC) for a rough surface target is designed, and the influences of both the numerical aperture of receiving system and rough target size on imaging performance of GISC are investigated and analyzed by using this setup. The results demonstrate that the imaging quality of GISC for the rough surface target is positive in relation to both parameters. This research could be considered as an instructive role for the optical system design of a GISC system.
