Abstract The existence of three generalized mirrors (Martinelli and Martelli, 2017) that compensate for the effects of birefringence in retracing optical circuits allows to develop a parallel with the time reversal properties. The Wigner time reversal operator for the photon spin is considered and three pseudo time reversal operators borrowed from this original operator are introduced and analysed. Their application to different birefringence situations demonstrates the validity and the fertility of the approach.

极化状态的伪时间反转算子

摘要 三个广义反射镜（Martinelli 和 Martelli，2017 年）的存在可以补偿回溯光路中双折射的影响，从而可以发展出与时间反转特性的平行关系。考虑了光子自旋的 Wigner 时间反转算子，并介绍和分析了从这个原始算子中借用的三个伪时间反转算子。它们在不同双折射情况下的应用证明了该方法的有效性和生育力。
