If a source of radiation is placed at the focus of the parabaloid then the energy will be reflected from the parabaloid into a beam whose beam width, in the ideal case, is determined by the diffraction limit associated with the diameter of the reflector.
若一个辐射源处于抛物面焦点上,其能量就会从抛物面被反射到光束内。 理想情况下,该波束宽度取决于反射器直径相关的衍射极限。
As the beam 24 is transported along the beam path toward the workpiece 30, the beam 24 encounters various electric and/or magnetic fields and devices that may alter the beam width and/or height.
由于射束24沿着射束路径朝着工件30传输,因此,射束24遇到各种电场和/或磁场以及可以改变射束宽度和/或高度的器件。
The result is that the beam width for radars is measured in tens of milliradian (mrad), compared to the resolution of optical sensors, which is of the order of tens of microradian (μrad).
