根据多普勒效应，光被离子反射后，靠近激光器的光的频率会高于远离激光器的光的频率，（日常生活中，救护车警报器的音调随着车的远近也变化，就是这个道理）这才有可能测量先前对离子施加的力的大小。
(An everyday example of this effect is the change of pitch of an ambulance siren as it approaches and recedes.) It was thus possible to measure the force applied to the ions.

MELP声码器采用混合脉冲和噪声激励解决了经典LPC的嗡嗡声的问题； 引入了抖动浊音状态以克服音调噪声；
MELP vocoders utilize mixed pulse and noise as the excitation to elimate the buzzes in traditional LPC vocoders, and add a jitter voicing state to overcome the tonal noise.
换句话说，它们只能用于录音和回放，而不是一个“循环”包含诸如环绕声处理器均衡器(用于音调控制)或其他电路。
In other words, they can only be used for tape recording and playback rather than for a "loop" containing an equalizer (for tone control) or other circuit such as a surround sound processor.
内置扬声器调整基准音调。
它是一种类似的多普勒频移的效应，就像救护车在你面前驶过时，会促使逐渐靠近你的警报器明显地改变其音调那样。
A similar effect, called the Doppler shift, causes the siren of an approaching ambulance to apparently change pitch as it passes you.
