Inline holographic microscopy through fibre imaging bundles. Fig. 6

This dataset and code provides an example for reconstructing fibre bundle inline holography videos of fresh pond water. A container holding the water was back illuminated by 450 nm LED light coupled through a multimode fibre with a 50 micron diameter core. The illumination fiber was approximately 15 mm behind the container wall. The hologram was collected by a Fujikura FIGH-30-650S fibre bundle approximately 500 microns on the other side of the wall. At the proximal end, this was imaged onto a CMOS camera via a 20X objective and a tube lens, giving an effective pixel size of 0.44 microns.

本数据集与配套代码提供了新鲜池塘水的纤维束同轴全息（fibre bundle inline holography）视频重构示例。实验中，盛放池塘水的容器由450nm LED光背照照明，该光线通过纤芯直径为50微米的多模光纤（multimode fibre）耦合注入；照明光纤位于容器壁后方约15毫米处。全息图由位于容器壁另一侧约500微米处的藤仓（Fujikura）FIGH-30-650S型纤维束采集。在光纤束近端，采集到的光信号通过20倍物镜（20X objective）与镜筒透镜（tube lens）成像至CMOS相机，最终获得有效像素尺寸为0.44微米的成像结果。
