| 英文摘要 | a simple method has been proposed to suppress artificial noise from the counts with respect to the central line (or point) for the reconstructed 3d images with cylindrical symmetry in the velocity-map imaging spectroscopy. a raw 2d projection around the z-axis (usually referred to as central line) for photodetachment, photoionization, or photodissociation experiments is pre-processed via angular tailored method to avoid the signal counts distributed near the central line (or point). two types of photoelectron velocity-map imaging (o- and au-center dot nh3) are demonstrated to give rise to the 3d images with significantly reduced central line noise after pre-processing operation. the major advantages of the pre-operation are the ability of suppression of central-line noise to resolve weak structures or vibrational excitation in atoms or molecules near photon threshold.
