A computational lensless phase microscope based on coherent diffraction is developed. Phase imaging with a pixel size limited resolution of 2.2 μm is achieved without the need for assumptions about the object or mechanically moving parts. Several diffraction patterns are recorded using an illumination pattern caused by coherent interference of two beams. This type of image reconstruction using multiple illumination patterns is called ptychography.
