We shown that the Wigner function of a cavity field can be reconstructed by knowing the position distribution of resonant two level atoms on detection screen. The atoms are deflected during their passage through the quantized cavity field, we calculate the momentum distribution of the deflected atoms by taking the Fourier transform of position distribution and show that how the Winger function can be reconstructed by having the knowledge of momentum distribution. In the proposed method, the Wigner function of the coherent state and Schrodinger cat state is recovered in a straightforward manner, without much mathematical manipulation of the experimental data.
