相干光 [xiāng gān guāng]
{光} coherent light
- 利用部分相干光理论，推导出柱坐标系下平顶高斯光束模相关系数的解析表达式。
By using the theory of partially coherent light, the analytical expression for the mode coherence cofficients of flattened Gaussian beams has been derived in the cylindrical coordinate system. - 摘要从理论上研究部分相干光被一环形透镜聚焦，在焦点附近的轴上点的光强分布。
The on-axis intensity distribution was investigated in the focal region of partially coherent light focused by an annular lens. - 利用光阑可对部分相干光的轴向偏振传输特性进行控制，对实际应用有重要的参考价值。
Thus the on-axial polarization distribution can be controlled by apertures, which is useful for the application of partially coherent light.
