VESCENT外差模塊
特點(diǎn):
動態(tài)平差底座-準(zhǔn)直輕松、快捷!
通過重疊主從激光器兩光束得到光學(xué)拍音信號
光功率輸入范圍大
直通式光束輸入
光學(xué)拍音信號通過光纖傳輸?shù)教綔y模塊
多模光纖,準(zhǔn)直簡單;單模光纖,信號最 da化
拍音監(jiān)視出口為自由空間,便于準(zhǔn)直
D2-250外差模塊經(jīng)過重新設(shè)計用于實(shí)現(xiàn)主從激光器兩光束的重疊從而得到光學(xué)拍音信號。新式的動態(tài)平差底座使得主從激光器兩光束的準(zhǔn)直更加輕松快捷。輸入接口的可旋轉(zhuǎn)玻片及偏振光束分束器的使用,使得當(dāng)接收到是大范圍功率范圍時可以輕松獲取外差所需要的小部分功率。該模塊光學(xué)拍音信號經(jīng)拍音探測器探測后轉(zhuǎn)換為電學(xué)拍音信號,并發(fā)送給D2-135偏移鎖相伺服器用于主從激光器之間的鎖定。
D2-135偏移鎖相伺服器將拍音信號同內(nèi)部參考信號或者客戶提供的外部參考信號進(jìn)行對比,將從激光器以預(yù)設(shè)的偏移量緊密鎖定到主激光器。D2-250易于準(zhǔn)直,只需要兩個激光器分別提供總功率中的很小一部分即可正常運(yùn)作。
