摘要
鉴于实际应用的需要,考虑角锥反射器的二面角加工误差,采用矩阵光学和矢量运算方法,建立了一套适合于数值模拟的角锥反射器的后向反射数学模型,给出了角锥后向反射器光束变换及衍射传输的公式和数值模拟计算方法。分别针对理想角锥后向反射器和有二面角加工误差的角锥反射器,研究了反射光束的传输特性,分析了入射角和传输距离对近场和远场能量分布的影响。根据卫星搭载角锥反射器的特殊要求,讨论了速差补偿方法和设计等问题,并针对卫星姿态控制的两种情况,分别提出了速差补偿的设计方案。
Abstract
A math model of cube corner retroreflector (CCR) with dihedral angles errors is built with matrix optics and vector operating methods. A numerical simulation method for studying the characters of beam reflected by CCR is presented. The characters of intensity distribution of the beam reflected by CCR at several propagation distance is simulated with numeric method. The propagation property and characters of energy profile in near field or far-field are studied. According to the condition of velocity aberration compensation, the design of the CCR for satellite aboard is discussed.
