- 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
本课题拟通过设计3mm开放式谐振腔,使开放式谐振腔中传播的高斯波束的束腰半径尽可能小,组建3mm准光学谐振腔测试系统,编写测试软件,对介质片进行测试,调节移动装置,实现对大面积介质片的扫描测试,从而测得介质片介电性能的分布。
