摘要	A technique for obtaining a three-dimensional distribution of received photons in Ha flares in the solar atmosphere is presented. It is well known that during flares hydrogen atoms in the chromosphere and photosphere are excited (even ionized) by the downward heating of non-thermal particles and then emit Ha. photons. We trace back these Ha photons to their original layers by use of the contribution function in the theory of spectral line formation, and so acquire their three-dimensional (3D) distribution. This technique is applied to the two-ribbon flare of 2002 January 20. The atmospheric models are obtained by fitting the "quasi-profiles" with the help of the generally used model atmospheres. Since the variety of the 3D images reflects the response of the atmospheric layers to the impact of energy transport, an analysis of the development of the flare is given through a comparison of the 3D images with the 2D temperature distribution.
