ABSTRACT:
An imaging method and an imaging device are disclosed which use no image forming optical system. A grid system 25 including an objective grid array 22 with a plurality of coplanarly arranged grids having pitches different from each other and a detector grid array 23 having a similarly enlarged configuration of the objective grid array, and a detector array 24 constitute a detection system. An energy ray such as an X-ray which has been transmitted through the grid system 25 is detected by the detector array 24 while rotating an object 20 under observation placed on a rotary table 21. A signal processing means 28 subjects signals detected by the detector array 24 to inverse Fourier transform to synthesize an image of the object 20, and the image is displayed on a display 29.
