We comment on a recent Letter [Opt. Lett. 35, 4121 (2010)], in which the authors discuss an optimal pulse-width modulation (OPWM) method for sinusoidal fringe generation. We consider that the comparison of the squared binary method (SBM) and the sinusoidal pulse-width modulation (SPWM) method has considerable deficiencies.
我们评论了最近的一封信[Opt. Lett. 35, 4121 (2010)]，其中作者讨论了用于正弦条纹生成的最佳脉冲宽度调制 (OPWM) 方法。我们认为，平方二进制方法 (SBM) 和正弦脉冲宽度调制 (SPWM) 方法的比较存在相当大的缺陷。
