TL;DR: ONE-BIT DIFFRACTION TOMOGRAPHY AND OPTIMAL DOSE FRACTIONATION
Abstract: We study 1-bit diffraction tomography with intensity-only binary measurements obtained through coded apertures and show numerically that with moderate oversampling, such a method is noise-robust. We investigate the problem of dose fractionation, revealing optimal performance at a signal-to-noise ratio near 1, independent of the total dose.
