Abstract
This paper presents a new way for making circular hologram gratings with high-density and equidistance, namely to use reflection interference formed by cone mirror to obtain circular interference with equal fringe spacing. The intensity distribution of interference field of reflection formed by cone mirror and the method for recording hologram gratings are given. The author suggests that this way for fabricating circular hologram gratings will find extensive use in optical testing and fiber-optic devices (such as DWDM and DBR).
