THE OPTICAL PARAMETERS OF SELFOCSAMPLE ARE MEASUED BY THE METHOD OF CUTTING THE LONG OR ADDUBG TI TGE SGIRT
以“截长补短”法测量自聚焦样品光学参数

In this paper the vertex focolength (intercept) methed is improved using the equallightpathity o f mys to pass focus,for it can be used to measure the focu-sing (quadratic gradient)constant and the axlal center index simultaneously.The derived fo rmula can be also used to examine products in pro bessing.
