摘　　要：本文介绍了设计及测试球平面准光学开放腔(准光腔)的过程,对腔内稳定振荡场分布、菲涅尔数进行了细致分析,阐述了球平面准光腔的设计制作要点,介绍了用于介质测试的准光腔扫频测量系统,并采用标量网络分析仪(SNA)对准光腔进行了品质因数测定。The paper introduced the designing process and measurement technology of a quasi - optic hemispherical open resonator that used for sweep frequency dielectric measurement system. The electromagnetic field and the Fresnel number of the quasi - optic resonator were analyzed and the outline of the resonator＇ s design was also presented. The Q factors of the quasi - optic resonator were measured by scalar network analyzer （SNA）.
