The task will be completed by designing 3mm quasi - optical resonator to get small waist radius of gaussian beam existing in quasi - optical resonators . the 3mm quasi - optical resonator test system is built and the test soft is written in vc + + language . we test on dielectric plates , then realize sweep test of large - area sample by adjusting move set to get dielectrical parameter distribution 本課題擬通過設計3mm開放式諧振腔,使開放式諧振腔中傳播的高斯波束的束腰半徑盡可能小,組建3mm準光學諧振腔測試系統(tǒng),編寫測試軟件,對介質(zhì)片進行測試,調(diào)節(jié)移動裝置,實現(xiàn)對大面積介質(zhì)片的掃描測試,從而測得介質(zhì)片介電性能的分布。
