在ZEMAX中,物理光学传播的功能里面空间余弦矩阵是怎么得到的,物理光学传播中光束的Y轴是怎么定义的,或者“镜头编辑器→物理光学→采用X轴参考”是什么意思?
Use X-axis Reference

In ZEMAX, how is the space cosine matrix obtained in the function of physical optical propagation, how is the Y-axis of the beam in physical optical propagation defined, or what does "lens editor → physical optics → Use X-axis Reference " mean?

Hi, 关于这部分,可以在说明书The Setup Tab > Editors Group (Setup Tab) > Lens Data Editor > Surface Properties > Physical Optics → Use X-axis Reference中找到相关的解答

By default, the grid of rays used to generate the transfer function at any surface is oriented such that the Y-axis of the grid aligns with the Y-axis of the beam. In highly tilted systems this choice of alignment may not be appropriate. This option allows the orthogonal choice of grid alignment, i.e. one in which the X-axis of the grid aligns with the X-axis of the beam.

谢谢你的解答。目前有个问题就是光线网格的方向是怎么定义的。或者就是光束Y轴参考和光线网格方向是哪个为先,以什么为定义标准。因为现在我们找不到这个方向是怎么定义的。

Thank you for your answer. The problem is how to define the direction of the grid of rays. Or just which comes first, the Y-axis reference of the beam or the direction of the grid of rays, and what is the defining criteria. Because right now we can't find how this direction is defined.
