A hard X-ray plenoptic camera works at ~8 keV and aims at imaging organs of small animals.
The first proof-of-concept – as illustrated in the figure – is based on the following characteristics:
- a hard X-ray condenser,
- a hard X-ray imaging optic,
- a 9×9 array of hard X-ray Fresnel Zone plates (see picture)
- coupled to the detector.
The set-up is ~2m long and the magnification is ~4.
