Inline holographic microscopy through fibre imaging bundles. Fig. 4.

This dataset and code provides an example for reconstructing inline holography images through a fibre imaging bundle. The sample is a USAF resolution target. The target 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 target. The hologram was collected by a Fujikura FIGH-30-650S fibre bundle approximately 0.75 mm in front of the target. 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.

本数据集及配套代码提供了一个通过光纤成像束（fibre imaging bundle）重建同轴全息图像的示例。实验样品为USAF分辨率靶标（USAF resolution target），该靶标采用450纳米LED背光照明，照明光线通过芯径为50微米的多模光纤（multimode fibre）耦合进入系统。照明光纤位于靶标后方约15毫米处。全息图由藤仓（Fujikura）FIGH-30-650S型光纤成像束采集，该探头位于靶标前方约0.75毫米位置。在光纤束的近端，通过20倍物镜与镜筒透镜将成像光路耦合至CMOS相机（CMOS camera），最终获得0.44微米的有效像素尺寸。
