聲光偏轉(zhuǎn)器可以用來掃描激光束。這是通過改變射頻驅(qū)動頻率實現(xiàn)的。隨機位置、連續(xù)線掃描和順序點偏移都是可能的。根據(jù)晶體、波長和光束大小，可以獲得超過250KHz的掃描速率。
最佳效率要求輸入激光束設置在布拉格角，這是驅(qū)動頻率的函數(shù)。當掃掠掃描激光束時，由于AOD只能在一個驅(qū)動頻率下進行光學對準，因此會產(chǎn)生布拉格角失配。一般來說，這將根據(jù)掃描范圍降低效率?？梢允褂靡韵聨追N技術(shù)來盡量減少這種影響:
離軸聲光偏轉(zhuǎn)器(OAD)利用雙折射晶體的非線性特性，將布拉格角頻率靈敏度降到很低。
電子束引導聲光偏轉(zhuǎn)器(“-BS")根據(jù)射頻驅(qū)動頻率對晶體內(nèi)的聲柱進行電子引導。這就要求換能器上的相控陣電極是具有2或4個射頻輸入。
