acoustooptic modulator meaning in Chinese

声光调制器

Examples

It is quite important that the stability of signal ’ s amplitude which is modulated by the acoustooptic modulator
声光调制器的输入调制信号的振幅稳定性就显得尤为重要。
The detecting accuracy of the beam drift would be improved , as a high performance acoustooptic modulator modulates the frequency of the laser beam drift signal far away from the power frequency , the double power frequency and high frequency noises
具体包括: 1 .利用声光调制器将光束漂移量信号调制到远离工频及其倍频干扰和高频噪声的频带段,以期提高光束漂移量的检测精度。
Based the research on the laser beam drift feedback control technique , analysing the beam drift and its frequency components , a laser beam directional stability method is studied in the thesis in detail , with its measurement and control circuit system that combines the laser beam intensity modulation and the beam drift feedback control technique . in this method , at first the laser beam intensity is modulated with the acoustooptic modulator , then the lock - in amplifier is applied to detect and demodulate the modulating signal , at last a feedback control signal is generated by the dsp control circuit at last , including : 1
本文在原有的激光光束漂移量反馈控制准直技术的基础上,对光束漂移量信号的数据和频谱进行了分析,重点研究了一种集声光调制光强与光束漂移量反馈控制准直技术于一体的激光光束方向稳定方法及其测控电路系统,该方法通过声光调制实现光强调制,接着通过锁相放大电路检测并解调调制信号,然后通过dsp控制电路进一步对光束的漂移量进行反馈控制。
