應(yīng)用領(lǐng)域	醫(yī)療衛(wèi)生,電子/電池,航空航天,汽車(chē)及零部件,電氣	掃描速率	250KHz

聲光偏轉(zhuǎn)器可以用來(lái)掃描激光束。這是通過(guò)改變射頻驅(qū)動(dòng)頻率實(shí)現(xiàn)的。隨機(jī)位置、連續(xù)線掃描和順序點(diǎn)偏移都是可能的。根據(jù)晶體、波長(zhǎng)和光束大小，可以獲得超過(guò)250KHz的掃描速率。

最佳效率要求輸入激光束設(shè)置在布拉格角，這是驅(qū)動(dòng)頻率的函數(shù)。當(dāng)掃掠掃描激光束時(shí)，由于AOD只能在一個(gè)驅(qū)動(dòng)頻率下進(jìn)行光學(xué)對(duì)準(zhǔn)，因此會(huì)產(chǎn)生布拉格角失配。一般來(lái)說(shuō)，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(lái)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(dǎo)聲光偏轉(zhuǎn)器(“-BS")根據(jù)射頻驅(qū)動(dòng)頻率對(duì)晶體內(nèi)的聲柱進(jìn)行電子引導(dǎo)。這就要求換能器上的相控陣電極是具有2或4個(gè)射頻輸入。
