| Abstract: | This paper mades a study of the image of Gaussian-type GRIN fiber lens by using a new method, ie, the "quasi-parabolic-type" equivalent method. The applicable conditions of this method are analysed and when the conditions are satisfied, the gaussian parameter calculating results based on this method are quite conincident with those obtained by solving the paraxial ray equation numberically. |
