论文摘要
我们建议使用高数值孔单模式光纤（例如光子晶体纤维），用于无透镜在线全息显微镜。高度发散的光束有助于克服图像传感器的空间采样限制。在本文中，已经证明了亚微米的横向分辨率，其中具有像素沥青1.12千分尺的成像传感器和模式场直径1.8微米的光子晶体纤维。在较早的单发透镜成像的方法中，在很小的工作距离和视场中获得了亚微米分辨率。提出的方法改善了分辨率，而不会损害工作距离。已经证明了（但不限于）〜1.7毫米的工作距离〜1.4 mm。
We propose to use high numerical aperture single mode optical fibers like photonic crystal fiber for lensless in-line holographic microscopy. Highly divergent beam helps to overcome the spatial sampling limitation of the image sensor. In this paper, a submicron lateral resolution has been demonstrated, with an imaging sensor of pixel pitch 1.12 micrometer and a photonic crystal fiber of mode field diameter 1.8 micrometer. In earlier methods of single-shot lensless imaging, submicron resolution has been obtained at very small working distance and field of view. The proposed method improves the resolution without compromising the working distance. A working distance of (but not limited to) ~1.7 mm with a field of View ~1.4 mm has been demonstrated.
