The theory of speckle formation in laser scanning display system is established based on the averaging effect of eye response as laser beam scanning through an eye resolution spot.

基于人眼对系统扫描人眼分辨斑过程的平均效应，建立了激光扫描显示系统中散斑的形成理论。

The highest speed of the irradiation bed can be determined by the frequency of modulator, scanning width, and the size of electron beam spot...

根据速调管调制器主振脉冲频率、扫描宽度和电子束的束斑大小可以定出辐照床的最高运动速度以实现高效率的辐照。

With this, the scanning beam is not directed at any single spot, but moves around, so the plastic does not burn.
