Abstract: | The multiple-beam interference fringes of Fabry-Perot etalon and con-focal spherical sweeping inter-ferometer in the vicinity of the con-focal point are observed. According to the change rules of the interference patterns and signal strength of interferometer fringes spectrum,the adjusting method of the con-focal point are introduced.The efficiency of the experiment are improved and get better results. |
