Main character of this apparatus is that the experimental phenomena are displayed by acoustic-optic indicator.

该装置的主要特点是采用声光显示实验现象。

Compared with conventional tunable acoustic-optic filters the present filter offers more narrow bandwidth and faster tuning speed.

该滤波器与通常的声光可调滤波器相比，带宽更窄，调谐速度更快。

The theoretical results show placing the acoustic-optic Q-switch crystal near the output mirror can improve the stability of pulse train.

计算表明：Q开关放置在输出镜一侧会使脉冲序列更加稳定。

As if the nation's overexcited and misguided border vigilantes didn't have enough ways to trigger alarms and bedevil the U.S. Border Patrol (whose job is hard enough as it is), University of Arizona researchers have developed Helios, a monitoring system that uses an acoustic sensor to detect movement via fiber optic cables buried beneath the US-Mexico border.
