beam-divergence angle的意思|示意

Another important application of diffraction theory is the study of the far field divergence Angle of a collimated light beam.

衍射理论的另一个重要应用就是研究准直光束的远场发散角。

The relative errors of the beam width and far-field divergence angle introduced by the spherical aberration increase with increasing spherical aberration coefficient and decreasing beam order.

束宽和远场发散角的相对误差随球差系数绝对值的增加和光束阶数的减小而增加；

The output parameters such as beam divergence angle in far-field output power of high power solid state lasers are variable due to thermal effect of optical pumping.

由于光泵浦热效应，高功率固体激光器的输出参数如光束远场发散角、输出功率等会发生变化。

According to acquisition and tracking strategy and laser detection theory, an expression of the best Angle of beam divergence under direct detection is provided.

根据捕获跟踪策略和激光检测理论，给出了直接探测情况下最佳光束发散角的表示式。

Finally by analyzing these data we can obtain the parameters about the laser beam such as: beam size, relative beam power, relative peak power, divergence Angle, M2 factor and so on.

通过分析这些数据可以获得有关光束的一些参数，如光斑尺寸、相对光功率、相对峰值功率、发散角、M2因子等等。

This method in the invention is only measuring in the one position of the optical path; therefore the method can facilitate to realize the real-time measurement of the beam divergence Angle.

本发明方法只在光路中的一个位置测量即可，因此本发明方法可方便地实现光束发散角的实时测量。
