聲光(guang)(guang)(guang)偏(pian)(pian)轉(zhuan)(zhuan)器，簡稱AOD、AODF，指利用聲光(guang)(guang)(guang)效(xiao)應來(lai)控(kong)制和偏(pian)(pian)轉(zhuan)(zhuan)激(ji)光(guang)(guang)(guang)束(shu)方向的(de)光(guang)(guang)(guang)學(xue)器件。聲光(guang)(guang)(guang)偏(pian)(pian)轉(zhuan)(zhuan)器具有穩定(ding)性好、響應速度(du)快、體積小、輕(qing)量化、功耗低、分(fen)辨率(lv)高等優勢，在(zai)光(guang)(guang)(guang)通信、光(guang)(guang)(guang)束(shu)掃描、光(guang)(guang)(guang)譜學(xue)、材(cai)料加工、無(wu)損測(ce)量、半導體檢測(ce)等眾多領(ling)域有所應用。聲光(guang)(guang)(guang)偏(pian)(pian)轉(zhuan)(zhuan)器種類較(jiao)為豐富，主(zhu)要包括表面(mian)波聲光(guang)(guang)(guang)偏(pian)(pian)轉(zhuan)(zhuan)器、鈮酸(suan)鋰(li)聲光(guang)(guang)(guang)偏(pian)(pian)轉(zhuan)(zhuan)器、硅(gui)聲光(guang)(guang)(guang)偏(pian)(pian)轉(zhuan)(zhuan)器等。

聲(sheng)(sheng)光(guang)偏轉器(qi)通常由電(dian)聲(sheng)(sheng)換能(neng)(neng)器(qi)以(yi)(yi)及聲(sheng)(sheng)光(guang)介質兩部分構成。電(dian)聲(sheng)(sheng)換能(neng)(neng)器(qi)采用(yong)壓電(dian)陶瓷為(wei)基材制成，能(neng)(neng)將電(dian)信號(hao)轉變(bian)為(wei)超聲(sheng)(sheng)波信號(hao)；聲(sheng)(sheng)光(guang)介質主要包括鈮酸(suan)(suan)鋰晶(jing)體、碲酸(suan)(suan)鋰晶(jing)體以(yi)(yi)及玻璃等(deng)，以(yi)(yi)上(shang)材料均具備(bei)聲(sheng)(sheng)光(guang)活(huo)性。

聲光偏轉器作為光電子器件(jian)，在眾多領域(yu)應用廣泛。未(wei)來伴隨市(shi)場(chang)需求增(zeng)長，我國(guo)聲光偏轉器行業(ye)景氣度將(jiang)進(jin)一(yi)步提(ti)高。
