Soft X-ray plenoptic camera

A soft X-ray plenoptic camera works at ~0.4 keV and is dedicated to biological cell imaging. The first proof-of-concept experiment – as illustrated in the figure – is based on the following characteristics:

– a vacuum chamber of 64 x 44 cm².

– a soft X-ray source from a laser-driven plasma

– an optical arrangment made of a soft X-ray condenser, a soft X-ray Fresnel zone plate (18nm outer zone width), a matrix of 20 x20 soft X-ray microlenses. Each microlens is a soft X-ray Fresnel zone plate with 1.7µm outer zone width. The total magnification is approximately 10.
