摘要
提出一种具有深度值的莫尔轮廓图。将一称为高标的正圆锥与被测物一起置于粗光栅之后 ,平行光照明 ,远场拍照。在所拍图片上高标的高度值 (已知 )除以高标上的等高线数即可求得相邻等高线的深度值 。
A moire contour drawing with the quantity of depth is presented. A regular cone, considered as an object to be used to mark height, is set behind a coarse grating with another object to be measured. Parallel light is used to illuminate the grating and the Moire drawing is taken photo in a remote place. So the quantity of the object to be used to mark height divided by the quantities of contour lines on it is the quantity of depth that one contour line adjoins the next one. As a result, the quantity of depth that is from any point to the normal one can be obtained directly by the Moire contour drawing.
