一、光栅莫尔技术的发展概况当两块光栅以微小交角相对倾斜重迭时,在与光栅刻线大致垂直的方向上,将看到明暗交替的条纹,这就叫莫尔条纹(Moire’ Fringe)。 1874年,瑞利(Rayleigh)首先应用莫尔原理检验光栅刻线的均匀性,随后逐步得到了发展,形成莫尔计量这一门科学。 First, the development of the grating Moir Technology Overview When the two rasters at a slight angle of inclination of the relative overlap, in the grating with the line roughly perpendicular to the direction, you will see alternating light and dark stripes, which is called the moire ’ Fringe). In 1874, Rayleigh first used Moore’s principle to test the uniformity of grating lines, and then gradually developed to form Moore’s metrology.
