光束偏转 meaning in Chinese
light beam deflection
optical beam deflection
Examples
- In a laser printer , a device that uses a modulator crystal to deflect a beam of light and effectively turn it on or off
在激光印刷机中的一种装置,它利用一块调制晶体使光束偏转并将其接通或断开。 - Beam steering characteristics of liquid crystal optical phased array ( lcopa ) is an important index evaluating its optical performance , and beam steering angle is the direct parameter indicating this
液晶光学相阵列的光束偏转特性是评价其光学特性的一项重要指标,而光束偏转角是直接评价这一特性的物理参数。 - This method doesn ’ t need beam deflection device and can change the reference beam incidence angle with mechanical movement platform only . and the accuracy of system is not getting lower
这种方法不需要光束偏转器件,只需要机械运动平台,仅通过平台的移动,就可以实现参考光束入射角度的变化,而且寻址的精确性并未降低。 - The beam steering angle is always small , about 2 ~ 3 , and high resolution and orientation precision are required , so a high - precision optical small - angle measurement technique and system is imminently required to develop
由于该光束偏转角一般比较小,大概在2 ~ 3 ,要求实现高的分辨力和定位精度,因此迫切需要研究一套高精度的光学小角度测量技术与系统。 - In this paper , dual - beam transmission problem that possess to a certainty included angle and gains the nonlinear schrdinger coupled equation ( nnlse ) in self - defocusing media is discussed
摘要自散焦介质中双光束斜入射耦合能发生光束偏转，通过数值模拟发现在非线性折射率不是均匀分布时光束偏转能降低抽运光功率并且偏转角度不减小，在相同的功率条件下，能产生更大的偏转。
