Inline holographic microscopy through a fibre imaging bundle. Fig. 3.

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.
