%X Poisson line technique is a method of generating a straight line by diffraction for high precision alignment,which can keep the center of Poisson spot in this line at long distances(several tens or hundreds of meters).Numerical simulation and experimental demonstration are proposed to research this technique.The intensity of the line increases asymptotically to the incident intensity as distance from the disk increases.The diameter of the line increases as the distances from the disk increases.Whereas it de...
