We present the extension of ptychograhpy for three-dimensional object reconstruction in a tomography setting. In this talk, we describe a general inversion framework for recovering an object from ptychographic measurements. We use the alternating direction method of multipliers (ADMM) algorithm to efficiently solve the nonlinear optimization problem. We demonstrate significant improvement of reconstruction quality compared with the commonly used sequential reconstruction approach.
