We present a method for single-shot blind deconvolution in coherent diffraction imaging. In our method, a complex amplitude object is illuminated with coherent light, and light from the object is captured through a coded aperture located on the pupil plane to reduce estimated variables. The complex amplitude field of the object is recovered from the single captured intensity image by a phase retrieval algorithm in which the coded aperture is utilized as a support to estimate the sparse pupil function. We numerically and experimentally demonstrate the proposed method. In the experiment, we evaluate its performance with ptychography, which is a method for multi-shot coherent diffraction imaging.
