光阑孔径 aperture of the diaphragm
- 硬边窄缝光阑孔径函数;
Hard-edge narrow slot aperture function; - 结果证明,孔径光阑的位置和尺寸直接影响激光输出模式和花样。
It is shown that the position and size of the aperture diaphragm directly impact on the output modes and patterns in the circula… - 这不是星星自身的光环,而是由于望远镜的圆形孔径光阑以及光的物理特性造成的。
This is not the star’s disk you are seeing but the effect of having a circular aperture in your telescope and due to the nature of light.
