Off-axis multi-slit coding for tomographic X-ray imaging of microplasma

Abstract Off-axis multi-slit coding is proposed for the imaging of X-rays emitted by laser-produced microplasmas. Unlike usual coding aperture techniques based on a two-dimensional reconstruction, our code allows a reconstruction with a mainly one-dimensional algorithm, without loosing the tomographical capability, which is provided by the off-axis location of slits in the coding mask.
