光电成像系统超分辨成像技术方法研究

Super-resolution imaging technology for optical imaging system

提出一种提高现有光电观瞄系统成像空间分辨率的新方法。在不改变阵列探测器件像元尺寸和不移动探测器的前提下,利用双光楔的较大移动使像平面发生微小位移,实现对探测器各相邻像元和不感光间隔目标进行微位移采样,提高目标信息的采样率,通过超分辨重建技术来提高系统的分辨能力,达到提高光电观瞄系统空间分辨率的目的。实验结果表明:该方法绕开了微小位移探测器需要克服的技术难题,同时避开了直接减少像元尺寸的工艺问题,且成像分辨率高。

A new method to improve the spatial image resolution of electro-optical sighting system is proposed.The movement of the optical double wedge was used to change the position of the imaging plane slightly.The micro-displacement sampling of the adjacent pixels and the targets in blind areas were realized without decreasing the size of the detection pixel or moving the target.The sampling rate was increased and the resolution of this system is improved using the super-resolution reconstruction technique.The experiments indicate that the method is simple and feasible,and the spatial image resolution is improved.
