Title: Rank-1 accelerated illumination recovery in scanning diffractive imaging by transparency estimation.

Illumination retrieval in scanning diffractive imaging a.k.a. ptychography is challenging when the specimen is weakly scattering or surrounded by empty space. We describe a rank-1 acceleration method for weakly scattering or piecewise smooth specimens.
