Optimal pulse width modulation for sinusoidal fringe generation with projector defocusing: reply to comment

We found that there were some inaccurate comments in the Comment by Ayubi and Ferrari [Opt. Lett.36, xxxx (2011)OPLEDP0146-9592] on our optimal pulse width modulation Letter [Opt. Lett.35, 4121 (2010)OPLEDP0146-959210.1364/OL.35.004121]. This Letter is to clarify some of the technical misunderstandings.
