| Abstract: | After studies on the optical image system of micro-displacement measurement based on the laser triangulation measurement,the concept of slantwise magnification was put forward and its formula was proved.The slantwise magnification can give a help to design of optimized optical image system easily and calculate the size of image accurately.Through particular analyzing the points of the spot's image with slantwise magnification,the secret of spot's image was opened out. |
