The aim of this paper is to compare the Ronchi test and the Moiré deflectometry applied to a new pattern. To do so, we used two Ronchi patterns (typical Ronchigrams) produced by two identical Ronchi rulings angularly displaced and placed close to the curvature radius of a mirror. The result obtained by superposing both Ronchigrams is our new pattern, a Moiré pattern of the Ronchigram (Moiré-Ronchigram). The Zernike aberration polynomial coefficients of the tridimensional wavefront for both mirrors are obtained as a result. We also compared the Zernike coefficients obtained for each of the mentioned techniques and we found that the results with less dispersion are those where Moiré deflectometry was applied. Finally, as a confidence test for applying and testing the Moiré-Ronchigram, we compare our results with Open Fringe, FringeXP, and APEX, using the root-mean-square and standard deviation values.
本文的目的是比较应用于一种新模式的朗奇测试和莫尔偏折术。为此，我们使用了由两个相同的朗奇光栅产生的两个朗奇图案（典型的朗奇图），它们在角度上有位移，并放置在靠近镜子曲率半径的位置。将这两个朗奇图叠加得到的结果就是我们的新模式，即朗奇图的莫尔图案（莫尔 - 朗奇图）。由此得到了两个镜子的三维波前的泽尼克像差多项式系数。我们还比较了通过上述每种技术获得的泽尼克系数，发现色散较小的结果来自应用莫尔偏折术的情况。最后，作为对应用和测试莫尔 - 朗奇图的置信度测试，我们使用均方根和标准差数值，将我们的结果与Open Fringe、FringeXP和APEX进行了比较。
