The three-dimensional (3D) image of an Hα flare is reconstructed from its line-center and seriary off-center filtergrams. The reconstruction is based on the principle of the line formation theory that the contribution function (CF) of emergent specific line intensity describes the escape photon distribution from stellar atmospheric layers. Thus the reconstruction depends on the model atmosphere accepted which determines the CF. An Hα flare taking place on April 22, 1992 is utilized to illustrate the process.
