摘要：

The 3-D velocity distribution of ionized photofragments resulting from the dissociation of methyl iodide is recovered by digitally deblurring and Abel inverting a single measured 2-D projection. The reconstructed distribution reveals two rings which are the dissociation channels corresponding to ground state and excited state iodine. A factor of 1.6 in resolution improvement of the channels is achieved by deconvolving the 2-D projection using a line-by-line implementation of Kawata's reblur algorithm. This technique guarantees noise-smoothed projections for the notoriously sensitive Abel inversion procedure, which in this paper is implemented using discrete Fourier and Hankel transforms.
