We report a simple real time optical imaging concept using an axicon lens to image the object kept behind opaque obstacles in free space. The proposed concept underlines the importance and advantages of using an axicon lens compared to a conventional lens to image behind the obstacle. The potential of this imaging concept is demonstrated by imaging the insertion of surgical needle in biological specimen in real time, without blocking the field of view. It is envisaged that this proposed concepts and methodology can make a telling impact in a wide variety of areas especially for diagnostics, therapeutics and microscopy applications.
我们报告了一种简单的实时光学成像概念，该概念使用轴棱锥透镜对自由空间中置于不透明障碍物后面的物体进行成像。与传统透镜相比，所提出的概念突出了使用轴棱锥透镜对障碍物后面的物体进行成像的重要性和优势。通过对手术针插入生物样本的过程进行实时成像，且不遮挡视野，证明了这种成像概念的潜力。可以设想，这一提出的概念和方法能够在广泛的领域产生显著影响，特别是在诊断、治疗和显微镜应用方面。
