The primary mirror . this is the paraboloidal mirror at the bottom of the tube . it has an aluminized surface that reflects starlight to form an image at the focal plane 主镜。是位于镜筒底部的一块抛物面镜。表面镀铝膜,将星光反射到焦平面上成像。

The combination of fdtd method with physical optics is also used to analyze paraboloidal reflector antenna in millimeter band . using fdtd method , we obtains precise near fields of the feed because the computing areas include all the feed structure . the current on the paraboloidal reflector can be calculated by using physical optics , and then the far field of reflector can be calculated 在毫米波抛物面天线的分析计算中,把fdtd与物理光学法结合起来, fdtd用于具有精细结构的馈源及馈电波导一体计算,得到馈源的幅度和相位方向图,以此为依据调整馈源结构,使馈源的幅度和相位方向图为最佳状态。
