A single shot PIE (ptychographic imaging engine) imaging method is proposed to overcome the disadvantages of common PIE algorithm. In this proposed method, a multiple beam illumination obtained with a cross grating is used to illuminate the object studied, and a CCD camera is adopted to record the diffraction pattern array of all the illumination beams simultaneously. The phase and the modulus images of the object can be faithfully reconstructed with stand PIE computation algorithm from the recorded data.
