摘要:

测量光的时空相关性为克服标准成像的传统局限性(如空间分辨率与景深之间的强权衡)提供了有趣工具。特别是,利用相关光场成像,可以同时探测场景中光的空间分布和方向,将分辨率和景深均推向波动光学所设定的基本极限。这使得无需任何空间扫描即可对不同轴向平面进行重聚焦和三维重建。在本工作中,我们通过考虑周期性测试图案,研究了一种特定相关光场成像方案中的分辨率极限。这些图案通过解析结果,为这种二阶成像技术的分辨率特性提供了更深入的见解,并与标准成像进行了比较。

英文摘要:

The measurement of the spatio-temporal correlations of light provides an interesting tool to overcome the traditional limitations of standard imaging, such as the strong trade-off between spatial resolution and depth of field. In particular, using correlation plenoptic imaging, one can detect both the spatial distribution and the direction of light in a scene, pushing both resolution and depth of field to the fundamental limit imposed by wave-optics. This allows one to perform refocusing of different axial planes and three-dimensional reconstruction without any spatial scanning. In the present work, we investigate the resolution limit in a particular correlation plenoptic imaging scheme, by considering periodic test patterns, which provide, through analytical results, a deeper insight in the resolution properties of this second-order imaging technique, also in comparison with standard imaging.
