laser passing

基本解释

The laser beam passing through the focusing systems gets an facula, which consists of main spot and sidelobe on the focus plane.
由於光的衍射作用，使通過聚焦系統的激光束入射到特定靶麪成一光斑（主光斑），而在主光斑以外還有次級光斑圈（旁瓣）。
When imprinted on silicon glass, these converters are able to alter the polarization of ultra-short pulses of laser light passing through them.
這些轉換器在被壓印到矽玻璃上之後，能改變通過它的超短脈沖激光的偏振方式。
In this paper, the investigation of the variations of the peak power and phase angle of a laser beam passing through a turbulent shear layer is discussed.
本文論述一個由流躰力學和光學聯系起來的新課題——激光通過湍流剪切層後的相位變化及峰值功率變化。

They have been testing a laser system for measuring lunar dust and soil kicked up by rocket exhausts, and while using precipitation as a substitute to calibrate the laser, they found they could measure the average size of raindrops passing through it.
