The method of constrained iteration is used to deconvolve measured histograms of intensity fluctuations of a laser beam propagated through atmospheric turbulence. The histograms are blurred by noise and background contributions in consequence of the combination law of probability-density functions. The deconvolution is applied first without constraint and then with the physical condition of positivity of the counting values. A criterion for properly stopping the iteration is also presented. The results are checked by evaluating the moments and comparing them with those previously obtained from direct noise and background removal.
