X-ray phase imaging with grating interferometers, such as the Talbot interferometer, is widely performed even with a laboratory X-ray source. However, the achievable spatial resolution is normally limited by the period of gratings. In this work, two laboratory-based apparatuses are developed to overcome the constraint of the spatial resolution. One is the combination of a commercially available FZP-based X-ray imaging microscope and Lau interferometer optics. The two-step deconvolution approach is explained to attain phase tomography. The other is a sub-period super-resolution X-ray phase imaging, which is based on the sample-scanning scheme across the beamlet array formed by a triangular phase grating. A proof-of-concept result of the super-resolution approach is presented.
