The phenomenon of Optical Phase Conjugation (OPC) can be rigorously simulated using the pseudospectral time-domain (PSTD) technique. However, with finite computational memory, it is infeasible to simulate light propagating long optical paths. We report a robust OPC simulation technique that can account for long optical path lengths by sequentially inverting the electromagnetic fields. Specifically, the ideal efficiency of OPC refocusing of light through scattering medium can be accurately determined.
光学相位共轭（OPC）现象可以使用伪谱时域（PSTD）技术进行精确模拟。然而，由于计算内存有限，模拟光在长光路上的传播是不可行的。我们报告了一种强大的OPC模拟技术，该技术可以通过依次反转电磁场来考虑长光程。具体而言，可以准确确定光通过散射介质进行OPC重新聚焦的理想效率。
