In this work, we present a panoramic digital holographic system for the first time capable of obtaining 3D information of a quasi-cylindrical object by using a conical mirror. The proposed panoramic digital holographic system is able to scan the entire surface of the object to determine the amplitude and phase simultaneously. This paper demonstrates the feasibility of analyzing quasi-cylindrical objects in a short time (0.5 s) with a single camera and a minimum number of optical components. In addition, it can be applied to determine not only topographic measurement of the cylindrical surface but also measurements of radial deformations. Experimental results are presented at different magnifications, thus illustrating its capabilities and versatility.

用数字全息和锥形镜全景重建准圆柱形物体

在这项工作中，我们首次提出了一种全景数字全息系统，能够通过使用锥形镜获得准圆柱形物体的 3D 信息。所提出的全景数字全息系统能够扫描物体的整个表面，同时确定幅度和相位。本文证明了使用单个相机和最少数量的光学元件在短时间内（0.5 秒）分析准圆柱形物体的可行性。此外，它不仅可以用于确定圆柱表面的形貌测量，还可以用于确定径向变形的测量。实验结果以不同的放大倍数呈现，从而说明了其功能和多功能性。
