一、前言莫尔条纹是由二片光栅相互作用产生的结果。图1(略)是很粗光栅形成的条纹示意图。宽带(即莫尔条纹)表示一光栅上的点对于另一光栅上点的相对位置。不论位移量等于移动光栅的节距或其整
First, the preamble Moire fringe is the result of two grating interaction. Figure 1 (omitted) is a very rough grating stripe diagram. Broadband (ie moiré) represents the relative position of a point on one raster to a point on another raster. No matter the displacement is equal to the pitch of the moving grating or its whole
