ASF單次自相關(guān)儀被設(shè)計(jì)用于監(jiān)測(cè)超快振蕩器和放大器的脈沖持續(xù)時(shí)間，以及用于實(shí)時(shí)放大器系統(tǒng)調(diào)諧。CCD攝像機(jī)寄存器的非共線生成輸入輻射（對(duì)SH是在非線性晶體產(chǎn)生）的二次諧波的橫截面。PC機(jī)的USB接口和Windows采集軟件提供流暢，方便數(shù)據(jù)轉(zhuǎn)換和登記，而附帶的LabView兼容的驅(qū)動(dòng)程序提供擴(kuò)展的靈活性和在線控制的復(fù)雜的多階段實(shí)驗(yàn)裝置。
ASF系列有四種基本模型，涵蓋了廣泛的操作波長(zhǎng)范圍。
應(yīng)用：
● 單次飛秒脈沖持續(xù)時(shí)間測(cè)量
● 復(fù)雜實(shí)驗(yàn)的設(shè)置自動(dòng)化
