摘　　要：采用退偏量和退偏相位表征退偏效应,当退偏量很小时,可忽略退偏相位,认为退偏效应很小;利用光学矩阵和坐标转换矩阵,建立了双角锥环形腔退偏量和退偏相位随角锥旋转变化的数学模型,并进行了数值模拟。分析结果表明,双角锥镜像对称排置构成环形腔时,可以在一定的偏振方位角的条件下实现退偏量为0,即无退偏效应;当旋转其中一个角锥小于2.5°时,仍可以得到小于0.09的退偏量;而当双角锥中心旋转对称排置时,退偏效应始终较大。The depolarization effect is taken with depolarization magnitude and depolarization phase, and it will be ignored as long as depolarization magnitude is very small, meanwhile depolarization phase also can be ignored. The math mode for depolarization magnitude and depolarization phase of this cross resonator when the comer cube reflector CCR was rotated was founded with the method of optic matrix and transition matrix. Then numerical simulation was taken. It indicates that depolarization magnitude can be zero under some conditions of polaration azimuth, when the two CCRs are arranged with enantiomorphous configuration; and depolarization magnitude will be less than 0.09 when the angle is less than 2.5 degree. However, depolarization magnitude will be always large when two CCRs are arranged with centrosymmetric configuration.
