title: Imaging 2-D objects with a grating interferometer: two methods.
abstract: Grating interferometric imaging has some unique advantages. The theory developed has been for 1-D objects only. The 2-D imaging methods reported are either complex or have low SNR. Two new methods for 2-D interferometric imaging are presented in this paper. The first is that an object composed of discrete points is imaged with a grating interferometer composed of three or more 1-D grating interferometers of which the grating line directions are different. The second is that a 2-D continuous distribution object is imaged with a 1-D grating interferometer by sampling line byline. These two methods are simple and may be practical for real time processing.
