A recent paper by Gao et al. [Appl. Opt. 44, 4870 (2005)] analyzed the performance of binary 0- π phase-only masks for an incident beam with Gaussian amplitude. Some inaccuracies of the analysis concerning the evolution of the Strehl ratio with the mask parameters are corrected.}, publisher = {Optical Society of America}, publisher = {Applied Optics, Vol. 46, Issue 2, pp. 180-181 (2007)}, title = {Comment on “Tunable three-dimensional intensity distribution by a pure phase-shifting apodizer”}, author = {Fernández Canales, Vidal and Otí González, José Emilio and Pérez Cagigal, Manuel}, }
